Description

Technical Field

[0001] This invention relates to a connecting device for connecting a first furniture component to a second furniture component. The invention also relates to a connecting device for connecting a third furniture component to a second furniture component. Furthermore, the invention relates to a tenon configured to attach to a tubular furniture component, which may be the second furniture component. The invention further relates to a connecting device for connecting a third furniture component to a second furniture component using tenons. The invention also relates to furniture comprising a first furniture component, a second furniture component, and a third furniture component, which are connected to each other using the aforementioned connecting device. Background Technology

[0002] In the field of furniture assembly, it is often necessary to connect furniture parts to each other. Furniture parts can be connected using fasteners such as screws or nails. The problem with these fasteners is that tools, sometimes specialized tools, are required to apply them. These fasteners are also often sensitive to incorrect positioning; for example, incorrectly hammering a nail can cause it to bend and / or damage the furniture part, or even cause personal injury. These tools can also be difficult to use, especially for disabled or elderly people. Furthermore, the fasteners themselves may be easily lost or pose a danger to children. Furniture parts can also be connected using different types of locks. However, these locks may also require many parts and may not provide a secure connection as they wear down over time.

[0003] For at least the reasons mentioned above, there is a need for better methods for connecting furniture components. Summary of the Invention

[0004] The object of this invention is to at least alleviate some of the problems mentioned in the background art.

[0005] This objective has been achieved by a connecting device for connecting the first furniture component to the second furniture component.

[0006] The first furniture component includes:

[0007] A tenon extending longitudinally from a first furniture component toward its free end, the tenon having at least one neck portion, and

[0008] One or more contact surfaces,

[0009] The second furniture component includes:

[0010] A through opening that extends through the wall of the second furniture component, and

[0011] One or more abutting surfaces are located on a first side portion of the wall, the first side portion facing a direction opposite to the longitudinal direction, and the one or more abutting surfaces extend circumferentially at least partially around the through opening or are distributed circumferentially at least partially around the through opening.

[0012] The connecting device further includes a connecting member having a recess with a locking portion configured to receive a tenon by relative movement between the connecting member and the first furniture component in a direction transverse to the longitudinal direction, and the locking portion configured to interact with the neck portion of the tenon to prevent the tenon from being removed from the locking portion in the longitudinal direction.

[0013] The first furniture component and the second furniture component are configured to be connected to each other in the following way:

[0014] The tenon is inserted from the first side through the through opening in the longitudinal insertion direction, and the abutting surfaces of the first furniture component and the second furniture component come into contact with each other.

[0015] The connecting member is positioned on the second side of the wall opposite the first side, and the connecting member is moved relative to the tenon in the transverse direction of travel, causing the tenon to slide into the locking portion.

[0016] The abutting surface of the first furniture component has a longitudinal extension along a portion of the tenon, and the abutting surface of the first furniture component extends circumferentially around the tenon at least partially or is distributed circumferentially around the tenon at least partially.

[0017] The abutting surface of the second furniture component extends from the first side of the wall in a direction opposite to the longitudinal direction, and the abutting surface of the second furniture component extends circumferentially around the through opening in at least a portion or is distributed circumferentially around the through opening in at least a portion.

[0018] Wherein, one or more abutting surfaces of the first furniture component and one or more abutting surfaces of the second furniture component are positioned on the respective furniture components such that when the tenon is inserted into the through opening, one or more abutting surfaces of the first furniture component abut against one or more abutting surfaces of the second furniture component, and impede relative movement between the first furniture component and the second furniture component in all directions transverse to the longitudinal direction, preferably transverse to the longitudinal direction.

[0019] The second furniture component will thus be correctly positioned and oriented relative to the first furniture component, and the connecting member can be easily moved while still providing a strong and stable connection between the first and second furniture components.

[0020] It is noteworthy that the terms "first," "second," and "third" are merely designations. The same designations are used for the same components throughout the specification and claims. This may lead to the possibility that a second and third furniture component might be referred to in a particular section of the specification relating to a specific connecting device, even though no first furniture component is mentioned in that context. However, it is noteworthy that since the terms "first," "second," and "third" are merely designations, it is conceivable that the furniture components be relabeled in different sections of the specification and in different claims, such that the designations "first," "second," and "third" are introduced, for example, in the order of appearance of that particular claim and incorporated into the associated description. However, since a single piece of furniture may include first, second, and third furniture components, and may include two or more different connecting devices disclosed herein, the same designations are used for the same components throughout the specification and claims, rather than relabeling them with respect to different connecting devices.

[0021] It is worth noting that the furniture components described can refer to different types of furniture. For example, furniture components may refer to individual freestanding furniture, such as shelves, bookshelves, TV cabinets, side panels, tables, and cupboards. Furniture components may also refer to built-in cabinets or shelves, such as wall-mounted kitchen cabinets and wall-mounted kitchen shelves. Furniture components may also refer to semi-built-in cabinets or shelves, such as wall-mounted TV cabinets. Whether furniture components are built-in or freestanding, they may not only refer to furniture designed for storage, such as cabinets and shelves, but also to furniture components used for other types of purposes. Furniture components may, for example, refer to furniture for sitting, such as sofas, benches, and chairs.

[0022] By providing a connecting device having a tenon, a through opening, abutting surfaces of a first furniture component and abutting surfaces of a second furniture component, and a connecting member formed to interact with the tenon and a second side of the second furniture component, a strong connection can be provided between the first furniture component and the second furniture component, and the connecting device can be assembled into a locking engagement without the use of any tools.

[0023] The design, featuring abutting surfaces, a surrounding through-hole, and positioning around tenons, provides a robust yet compact design. The design of the connecting device is particularly useful for joining tubular furniture components together, in which, specifically, the tubular shape of the first furniture component can serve as the abutting surface of the first component and can also be used to cover the connecting device.

[0024] Furthermore, the connecting member can, for example, be inserted through the opening end of the second furniture component, and can also be used to provide an end cover to the opening end.

[0025] One or more abutting surfaces of the first furniture component may include a tubular portion extending longitudinally and circumferentially around the base portion of the tenon. This design provides a robust abutting surface, facilitates its manufacture, and allows the connecting device to be concealed within the tubular portion. Preferably, a circumferentially extending gap exists between the base portion and the abutting surface formed by the tubular portion.

[0026] One or more abutting surfaces of the second furniture component are configured to be arranged inside and abutting one or more abutting surfaces on the interior of the tubular portion. This design provides robust abutting surfaces, facilitates the manufacture of abutting surfaces, and allows connecting devices to be concealed within the tubular portion.

[0027] One or more abutting surfaces of the second furniture component include tubular portions that extend from a first side of the wall in a direction opposite to the longitudinal direction and circumferentially around a through opening. This design provides a robust abutting surface and makes the abutting surface easy to manufacture.

[0028] The tenon of the first furniture component may include a base portion having an abutting surface adapted to abut the inner surface of the through-opening in the wall when the tenon is inserted. This can be used to provide a secure and distinctive positioning of the first furniture component relative to the second furniture component. If the base portion fits tightly into the through-opening, the first and second furniture components will be precisely positioned in any direction along the plane of the wall of the second furniture component.

[0029] The recess has an entry opening in a first surface, which together with a second surface forms a corner, the first surface intended to face the direction of travel and the second surface intended to face the wall of the second furniture component. This type of recess can be referred to as an open-end recess. Designing a connecting member with this recess makes it easy to use; the user can position the first and second furniture components in their intended positions and then push the connecting member through the tenon in a linear motion, thus connecting the first and second furniture components to each other. This design also facilitates the manufacture of the connecting member. The connecting member can be injection molded, for example, in a single-step process, because the entry opening can serve as a channel for the extraction of a removable core in the injection molding tool, wherein the core has the shape of the recess.

[0030] When viewed from the second surface along the depth direction, the recess has a depth that extends in the longitudinal direction, and when viewed along the depth direction, the recess may be provided with at least one neck portion configured to interact with the neck portion of the tenon. The neck portion may be formed by two opposingly arranged internal ridges extending along the second surface and facing each other. This design provides a strong connection and is easy to manufacture. This design is particularly suitable for combination with recesses with open ends because the ridges extending along the second surface allow for the extraction of a removable core in an injection molding tool. In a preferred embodiment, two neck portions are provided one after the other when viewed along the depth direction.

[0031] The first furniture component may be a tubular member having a main extension along the longitudinal direction, wherein a tenon is partially positioned in the open end of the tubular member such that the tenon extends partially inside the tubular member and extends partially beyond the tubular member along the longitudinal direction. As described above, preferably, there is a circumferentially extending gap between the base portion and the abutting surface formed by the tubular portion.

[0032] The tenon can be a separate element attached to the first furniture component. For example, the tenon can be attached to the first furniture component via an attachment portion positioned to extend further into the tubular member than the base portion.

[0033] The second furniture component can be a tubular member having an open end and a main extension, the open end facing the direction opposite to the direction of travel of the connecting member, and the main extension along the transverse direction. This is advantageous because the connecting member can be inserted into the tubular member and move in a single linear motion along the direction of travel to the locked position.

[0034] The aforementioned objective is also achieved by furniture comprising a second furniture component and a third furniture component, wherein the first furniture component and the second furniture component are connected to each other by a connecting device as introduced above and disclosed in more detail with reference to the detailed description and accompanying drawings.

[0035] The third furniture component is tubular, having an open end facing the longitudinal direction and a main extension along the longitudinal direction.

[0036] The second furniture component includes a tenon or is configured to receive a tenon, the tenon extending from the second furniture component toward its free end in a direction opposite to the longitudinal direction, wherein the tenon has at least one ridge, and when viewed along the longitudinal direction, at least one valley follows the ridge.

[0037] The second and third furniture components are connected to each other via a connecting device, which includes:

[0038] A connecting member having a recess and configured to be inserted through an open end and into a third furniture component.

[0039] The recess has a locking portion configured to receive the tenon via relative movement between the third furniture component and the connecting member in a direction transverse to the longitudinal direction, and the locking portion is configured to interact with the valley of the tenon to prevent the tenon from being removed from the locking portion in the longitudinal direction.

[0040] The second and third furniture components are configured to be connected to each other in the following ways:

[0041] The connecting member is at least partially inserted into the third furniture component, and

[0042] The third furniture component with the connecting member is moved relative to the tenon in the lateral direction of travel, causing the tenon to slide into the locking part of the connecting member.

[0043] By using a connecting member with a recess of this design and inserting the connecting member at least partially into a third furniture component, and by using a tenon of this design, a secure connection can be provided between the tubular furniture component and the second furniture component, and a connection device covered by a cover plate on the tubular furniture component and the tenon can be provided.

[0044] As mentioned above, it can be noted that the terms "first," "second," and "third" are merely designations. The same designations are used for the same components throughout the specification and claims. This results in the inclusion of references to a second and third furniture component in the specific section of the specification relating to that particular connecting device, even though no first furniture component is mentioned in that context. However, it can be noted that since the terms "first," "second," and "third" are merely designations, it is conceivable that the furniture components be relabeled in different sections of the specification and in different claims, such that the designations "first," "second," and "third" are introduced, for example, in the order of appearance of that particular claim and in the associated description. However, since a single piece of furniture may include the first, second, and third furniture components, and includes the initially disclosed connecting device as well as the connecting device just disclosed above, the same designations are used for the same components throughout the specification and claims, rather than relabeling them with respect to different connecting devices.

[0045] The tenon can be configured to attach to a tubular furniture component and to provide part of a connection device between the tubular furniture component and a third furniture component, thereby the tenon can include:

[0046] The connecting portion has at least one ridge, followed by at least one valley when viewed along the longitudinal direction, wherein the connecting portion is configured to extend from the second furniture component toward the free end of the tenon in a direction opposite to the longitudinal direction, and

[0047] The attachment portion has a neck portion, which, when viewed along the longitudinal direction, is followed by a head portion. The head portion has an extension in a first transverse direction that is larger than the extension of the neck portion along the first transverse direction, and larger than both the extensions of the head portion and the neck portion along a second transverse direction, which is orthogonal to the first transverse direction.

[0048] The tenon joint is constructed to be attached to the tubular furniture component in the following way:

[0049] The attachment portion is inserted into an elongated through-hole extending through the first wall of the tubular furniture component, wherein the tenon is oriented during insertion by aligning a first transverse direction with the longitudinal direction of the elongated through-hole, or by having at least a principal component of the first transverse direction along the longitudinal direction of the elongated through-hole, such that the head portion passes through the elongated through-hole, and thereafter...

[0050] The tenon is rotated in the first direction about an axis extending in the longitudinal direction, causing the head portion to interact with the interior of the wall, thereby preventing the head from being pulled out of the through opening.

[0051] These tenons are easy to attach to tubular furniture components, and they provide a secure connection by firmly attaching to the tubular furniture components and by providing a connecting portion that provides a secure connection using a recess having an internal ridge that interacts with the ridge and valley of the connecting portion.

[0052] When viewed along the first lateral direction, at least one end, preferably both ends, of the neck portion may have:

[0053] A rotating blocking corner is configured to interact with the edge of an elongated opening, thereby preventing the tenon from rotating about an axis in a second direction opposite to the first direction.

[0054] The rotation allows the corner portion to be configured to pass along the edge of the elongated opening, thereby allowing the tenon to rotate about the axis in a first direction.

[0055] Thus, the tenon can be rotated from its orientation when inserted to a desired orientation that prevents further rotation of the tenon.

[0056] Preferably, each of the two ends is provided with a rotation blocking corner and a rotation allowing corner, wherein the two rotation blocking corners are arranged diagonally opposite to each other, and the two rotation allowing corners are arranged diagonally opposite to each other.

[0057] The head portion can be asymmetrical in design and the elongated opening can be asymmetrical in design, such that the head of the tenon can only be inserted in one of two opposite orientations in the first transverse direction: in which the first transverse direction is aligned with the longitudinal direction of the elongated through retainer or has a major component along the longitudinal direction of the elongated through retainer.

[0058] Therefore, it can be controlled that the tenon can only be inserted in the orientation that results in the expected orientation of the tenon due to the combination of the rotation-blocking corner and the rotation-allowing corner.

[0059] In the connection device disclosed above for connecting a third furniture component to a second furniture component, the second furniture component may be a tubular furniture component having an elongated through opening extending through a first wall of the tubular furniture component, and the tenon may be designed according to the above disclosure in the most general term for tenon or in the preferred embodiment of tenon.

[0060] The elongated through opening preferably has a width along the transverse direction of the elongated through opening, which is larger than the extension of the head portion and neck portion along the second transverse direction and smaller than the extension of the head portion along the first transverse direction.

[0061] In a preferred embodiment, the present invention is conceived in furniture comprising a first furniture component, a second furniture component, and a third furniture component, wherein, as disclosed above in its most general terms or in the preferred embodiment, the first furniture component and the second furniture component are connected to each other by a connecting means for connecting the first furniture component to the second furniture component, and wherein, as disclosed above in its most general terms or in the preferred embodiment, the second furniture component and the third furniture component are connected to each other by a connecting means for connecting the second furniture component to the third furniture component.

[0062] The above objective is also achieved by a connecting device for connecting a third furniture component to a second furniture component.

[0063] The third furniture component is tubular, having an open end facing the longitudinal direction and a main extension along the longitudinal direction.

[0064] The second furniture component includes a tenon or is configured to receive a tenon, the tenon extending from the second furniture component toward its free end in a direction opposite to the longitudinal direction, wherein the tenon has at least one ridge, and when viewed along the longitudinal direction, at least one valley follows the ridge.

[0065] The connecting device also includes:

[0066] A connecting member having a recess and configured to be inserted through an open end and into a third furniture component.

[0067] The recess has a locking portion configured to receive the tenon via relative movement between the third furniture component and the connecting member in a direction transverse to the longitudinal direction, and the locking portion is configured to interact with the valley of the tenon to prevent the tenon from being removed from the locking portion in the longitudinal direction.

[0068] The second and third furniture components are configured to be connected to each other in the following ways:

[0069] The connecting member is at least partially inserted into the third furniture component, and

[0070] The third furniture component with the connecting member is moved relative to the tenon in the lateral direction of travel, causing the tenon to slide into the locking part of the connecting member.

[0071] By using a connecting member with a recess of this design and inserting the connecting member at least partially into a third furniture component, and by using a tenon of this design, a secure connection can be provided between the tubular furniture component and the second furniture component, and a connection device covered by a cover plate on the tubular furniture component and the tenon can be provided.

[0072] As mentioned above, it can be noted that the terms "first," "second," and "third" are merely designations. The same designations are used for the same components throughout the specification and claims. This results in the inclusion of references to a second and third furniture component in the specific section of the specification relating to that particular connecting device, even though no first furniture component is mentioned in that context. However, it can be noted that since the terms "first," "second," and "third" are merely designations, it is conceivable that the furniture components be relabeled in different sections of the specification and in different claims, such that the designations "first," "second," and "third" are introduced, for example, in the order of appearance of that particular claim and in the associated description. However, since a single piece of furniture may include the first, second, and third furniture components, and includes the initially disclosed connecting device as well as the connecting device just disclosed above, the same designations are used for the same components throughout the specification and claims, rather than relabeling them with respect to different connecting devices.

[0073] The above objective is also achieved by a tenon configured to attach to a tubular furniture component and to provide part of a connection device between the tubular furniture component and a third furniture component, the tenon comprising:

[0074] The connecting portion has at least one ridge, followed by at least one valley when viewed along the longitudinal direction, wherein the connecting portion is configured to extend from the second furniture component toward the free end of the tenon in a direction opposite to the longitudinal direction, and

[0075] The attachment portion has a neck portion, which, when viewed along the longitudinal direction, is followed by a head portion. The head portion has an extension in a first transverse direction that is larger than the extension of the neck portion along the first transverse direction, and larger than both the extensions of the head portion and the neck portion along a second transverse direction, which is orthogonal to the first transverse direction.

[0076] The tenon joint is constructed to be attached to the tubular furniture component in the following way:

[0077] The attachment portion is inserted into an elongated through-hole extending through the first wall of the tubular furniture component, wherein the tenon is oriented during insertion by aligning a first transverse direction with the longitudinal direction of the elongated through-hole, or by having at least a principal component of the first transverse direction along the longitudinal direction of the elongated through-hole, such that the head portion passes through the elongated through-hole, and thereafter...

[0078] The tenon is rotated in the first direction about an axis extending in the longitudinal direction, causing the head portion to interact with the interior of the wall, thereby preventing the head from being pulled out of the through opening.

[0079] These tenons are easy to attach to tubular furniture components, and they provide a secure connection by firmly attaching to the tubular furniture components and by providing a connecting portion that provides a secure connection using a recess having an internal ridge that interacts with the ridge and valley of the connecting portion.

[0080] When viewed along the first lateral direction, at least one end, preferably both ends, of the neck portion may have:

[0081] A rotating blocking corner is configured to interact with the edge of an elongated opening, thereby preventing the tenon from rotating about an axis in a second direction opposite to the first direction.

[0082] The rotation allows the corner portion to be configured to pass along the edge of the elongated opening, thereby allowing the tenon to rotate about the axis in a first direction.

[0083] Thus, the tenon can be rotated from its orientation when inserted to a desired orientation that prevents the tenon 51 from rotating further.

[0084] Preferably, each of the two ends is provided with a rotation blocking corner and a rotation allowing corner, wherein the two rotation blocking corners are arranged diagonally opposite to each other, and the two rotation allowing corners are arranged diagonally opposite to each other.

[0085] The head portion can be asymmetrical in design and the elongated opening can be asymmetrical in design, such that the head of the tenon can only be inserted in one of two opposite orientations in the first transverse direction: in which the first transverse direction is aligned with the longitudinal direction of the elongated through retainer or has a major component along the longitudinal direction of the elongated through retainer.

[0086] Therefore, it can be controlled that the tenon can only be inserted in the orientation that results in the expected orientation of the tenon due to the combination of the rotation-blocking corner and the rotation-allowing corner.

[0087] In the connection device disclosed above for connecting a third furniture component to a second furniture component, the second furniture component may be a tubular furniture component having an elongated through opening extending through a first wall of the tubular furniture component, and the tenon may be designed according to the above disclosure in the most general term for tenon or in the preferred embodiment of tenon.

[0088] The elongated through opening preferably has a width along the transverse direction of the elongated through opening, which is larger than the extension of the head portion and neck portion along the second transverse direction and smaller than the extension of the head portion along the first transverse direction.

[0089] The above objective is also achieved by a connecting device for connecting a third furniture component to a second furniture component.

[0090] The third furniture component is tubular, having an open end facing the longitudinal direction and a main extension along the longitudinal direction.

[0091] The second furniture component includes a tenon or is configured to receive a tenon, the tenon extending from the second furniture component toward its free end in a direction opposite to the longitudinal direction, wherein the tenon has at least one ridge, and when viewed along the longitudinal direction, at least one valley follows the ridge.

[0092] The connecting device also includes:

[0093] A connecting member having a recess and configured to be inserted through an open end into a third furniture component.

[0094] The recess has a locking portion configured to receive the tenon via relative movement between the third furniture component and the connecting member in a direction transverse to the longitudinal direction, and the locking portion is configured to interact with the valley of the tenon to prevent the tenon from being removed from the locking portion in the longitudinal direction.

[0095] The second and third furniture components are configured to be connected to each other in the following ways:

[0096] The connecting member is at least partially inserted into the third furniture component, and

[0097] The third furniture component with the connecting member is moved relative to the tenon in the lateral direction of travel, causing the tenon to slide into the locking part of the connecting member.

[0098] By using a connecting member with a recess of this design and inserting the connecting member at least partially into a third furniture component, and by using a tenon of this design, a secure connection can be provided between the tubular furniture component and the second furniture component, and a connection device covered by a cover plate on the tubular furniture component and the tenon can be provided.

[0099] As mentioned above, it can be noted that the terms "first," "second," and "third" are merely designations. The same designations are used for the same components throughout the specification and claims. This results in the inclusion of references to a second and third furniture component in the specific section of the specification relating to that particular connecting device, even though no first furniture component is mentioned in that context. However, it can be noted that since the terms "first," "second," and "third" are merely designations, it is conceivable that the furniture components be relabeled in different sections of the specification and in different claims, such that the designations "first," "second," and "third" are introduced, for example, in the order of appearance of that particular claim and in the associated description. However, since a single piece of furniture may include the first, second, and third furniture components, and includes the initially disclosed connecting device as well as the connecting device just disclosed above, the same designations are used for the same components throughout the specification and claims, rather than relabeling them with respect to different connecting devices.

[0100] The above objective is also achieved by a tenon configured to attach to a tubular furniture component and to provide part of a connection device between the tubular furniture component and a third furniture component, the tenon comprising:

[0101] The connecting portion has at least one ridge, followed by at least one valley when viewed along the longitudinal direction, wherein the connecting portion is configured to extend from the second furniture component toward the free end of the tenon in a direction opposite to the longitudinal direction, and

[0102] The attachment portion has a neck portion, which, when viewed along the longitudinal direction, is followed by a head portion. The head portion has an extension in a first transverse direction that is larger than the extension of the neck portion along the first transverse direction, and larger than both the extensions of the head portion and the neck portion along a second transverse direction, which is orthogonal to the first transverse direction.

[0103] The tenon joint is constructed to be attached to the tubular furniture component in the following way:

[0104] The attachment portion is inserted into an elongated through-hole extending through the first wall of the tubular furniture component, wherein the tenon is oriented during insertion by aligning a first transverse direction with the longitudinal direction of the elongated through-hole, or by having at least a principal component of the first transverse direction along the longitudinal direction of the elongated through-hole, such that the head portion passes through the elongated through-hole, and thereafter...

[0105] The tenon is rotated in the first direction about an axis extending in the longitudinal direction, causing the head portion to interact with the interior of the wall, thereby preventing the head from being pulled out of the through opening.

[0106] These tenons are easy to attach to tubular furniture components, and they provide a secure connection by firmly attaching to the tubular furniture components and by providing a connecting portion that provides a secure connection using a recess having an internal ridge that interacts with the ridge and valley of the connecting portion.

[0107] When viewed along the first lateral direction, at least one end, preferably both ends, of the neck portion may have:

[0108] A rotating blocking corner is configured to interact with the edge of an elongated opening, thereby preventing the tenon from rotating about an axis in a second direction opposite to the first direction.

[0109] The rotation allows the corner portion to be configured to pass along the edge of the elongated opening, thereby allowing the tenon to rotate about the axis in a first direction.

[0110] Thus, the tenon can be rotated from its orientation when inserted to a desired orientation that prevents the tenon 51 from rotating further.

[0111] Preferably, each of the two ends is provided with a rotation blocking corner and a rotation allowing corner, wherein the two rotation blocking corners are arranged diagonally opposite to each other, and the two rotation allowing corners are arranged diagonally opposite to each other.

[0112] The head portion can be asymmetrical in design and the elongated opening can be asymmetrical in design, such that the head of the tenon can only be inserted in one of two opposite orientations in the first transverse direction: in which the first transverse direction is aligned with the longitudinal direction of the elongated through retainer or has a major component along the longitudinal direction of the elongated through retainer.

[0113] Therefore, it can be controlled that the tenon can only be inserted in the orientation that results in the tenon's intended orientation due to its engagement with the rotation-blocking corner and the rotation-allowing corner.

[0114] In the connection device disclosed above for connecting a third furniture component to a second furniture component, the second furniture component may be a tubular furniture component having an elongated through opening extending through a first wall of the tubular furniture component, and the tenon may be designed according to the above disclosure in the most general term for tenon or in the preferred embodiment of tenon.

[0115] The elongated through opening preferably has a width along the transverse direction of the elongated through opening, which is larger than the extension of the head portion and neck portion along the second transverse direction and smaller than the extension of the head portion along the first transverse direction.

[0141] First refer to Figure 1 , Figure 2a and Figure 5a A connection device for connecting a first furniture component 10 to a second furniture component 20 is disclosed.

[0142] like Figures 2a to 2e As shown, the first furniture component 10 is tubular and has a main extension along the longitudinal direction L. The first furniture component 10 includes a tenon 11 and a tubular portion 10a forming an abutment surface 13. The tenon 11 extends from the first furniture component 10 along the longitudinal direction L toward its free end 11c. The tenon 11 has, for example, as shown in... Figure 2c The two neck portions 11b are indicated in the middle. The abutment surface 13 has an extension in the longitudinal direction L along the base portion 11a of the tenon 11. The abutment surface 13 also extends circumferentially C around the tenon 11. Figure 2d As shown, a circumferentially extending gap G13 exists between the base portion 11a and the abutting surface 13 formed by the tubular portion 10a. In the disclosed embodiment, the tenon 11 and the through opening 22 have a circular cross-section. However, the tenon 11 and the through opening 22 can have virtually any desired cross-sectional shape. From a manufacturing perspective, a circular shape is preferred. A non-circular shape may also be preferred from the perspective that it can be used to define a specific rotational relative orientation between the first furniture component 10 and the second furniture component 20 about the longitudinal direction L.

[0143] The second furniture component 20 is tubular and includes a through opening 22 and an abutment surface 23. The through opening 22 extends through the wall 21 of the second furniture component 20. The abutment surface 23 is formed by a tubular portion 23' that extends from a first side portion 21a of the wall 21 in a direction L' opposite to the longitudinal direction L. The abutment surface 23 also extends circumferentially C around the through opening 22. The second furniture component 20 has a main extension in a transverse direction T that is transverse to the longitudinal direction L.

[0144] It can be noted that, in the preferred embodiment, the first furniture component 10 is formed of a square or rectangular tube, and the abutting surface 13 extending around the tenon 11 is a continuous surface formed by the four sides of the cross-section of the square or rectangular tube.

[0145] like Figure 2c As shown, the abutting surface 13 of the first furniture component 10 and the abutting surface 23 of the second furniture component 20 are positioned on the respective furniture components 10 and 20 such that when the tenon 11 is inserted into the through opening 22, the abutting surface 13 of the first furniture component 10 abuts against the abutting surface 23 of the second furniture component 20, and prevents relative movement between the first furniture component 10 and the second furniture component 20 in all directions T transverse to the longitudinal direction L.

[0146] like Figures 2a to 2e The instructions in and in Figure 1As disclosed in more detail, the connecting device also includes a connecting member 30. The connecting member 30 has a recess 31 with a locking portion 31b configured to receive a tenon 11 by relative movement between the connecting member 30 and the first furniture component 10 in a direction T transverse to the longitudinal direction L, and the locking portion 31b is configured to interact with the neck portion 11b of the tenon 11 to prevent the tenon 11 from being removed from the locking portion 31b in the longitudinal direction L.

[0147] like Figure 1 As shown, the recess 31 has an entry opening 31a in a first surface 32a, which together with a second surface 32b forms a corner 32c. The first surface 32a is intended to face the direction of travel B, and the second surface 32b is intended to face the wall 21 of the second furniture component 20. This recess 31 can be referred to as an open-end recess 31. Figures 2b to 2d As indicated, the connecting member 30 with this recess 31 is easy to use; the user can position the first furniture component 10 and the second furniture component 20 in their desired positions, and then push the connecting member 30 through the tenon 11 in a straight-forward motion, so that the first furniture component 10 and the second furniture component 20 become connected to each other. This design also facilitates the manufacture of the connecting member 30. The connecting member 30 can be injection molded, for example, in a single-step process, because the inlet opening 31a can be used as a channel for the extraction of a removable core in the injection molding tool, wherein the core has the shape of the recess 31.

[0148] When viewed from the second surface 32b along the depth direction D, the recess 31 has a depth d31, with the depth direction D extending along the longitudinal direction L. When viewed along the depth direction D, the recess is provided with two neck portions 31c, 31c', which are configured to interact with the corresponding neck portion 11b of the tenon 11. When viewed along the depth direction D, the two neck portions 31c, 31c' are arranged one after the other. Alternatively, it can be said that the neck portions 31c, 31c' are located at different depths in the recess 31. Each neck portion 31c, 31c' is formed by two opposingly arranged internal ridges 33a, 33b extending along the second surface 32b and facing each other.

[0149] like Figure 1 The examples shown are as follows: Figures 2c to 2dAs shown, the connecting member 30 has a body portion 30' and an end portion 30'", in which a recess 31 is formed. The body portion 30' is configured to be inserted into the tubular member 20. The end portion 30' has a slightly larger dimension in the insertion direction B, and the end portion 30' is configured to close the end of the tubular member 20. The interaction between the end portion 30' and the end of the tubular member 20 can also be used for the connecting member 30 along the direction of insertion B. Figure 2e The arrow K in the diagram indicates the direction of movement B, which provides a stop.

[0150] like Figures 2a to 2e As indicated in the diagram, the first furniture component 10 and the second furniture component 20 are configured to be connected to each other by the following:

[0151] like Figure 2a As shown, the tenon 11 is inserted from the first side portion 21a through the through opening 22 in the insertion direction A along the longitudinal direction L, and as... Figures 2b to 2c As shown, the abutting surfaces 13, 23 of the first furniture component 10 and the second furniture component 20 are brought into contact with each other, and

[0152] like Figures 2b to 2c As indicated, the connecting member 30 is positioned on the second side 21b of the wall 21 opposite to the first side 21a, and the connecting member 30 is moved relative to the tenon 11 in the travel direction B along the transverse direction T, such that the tenon 11 slides into the locking portion 31b and slides to... Figure 2d The location indicated in the middle.

[0153] The connecting member 30 is positioned on the second side 21b by being inserted through an open end 20c that passes through the second furniture component 20, the open end 20c facing a direction B' opposite to the direction of travel B of the connecting member 30.

[0154] like Figure 2d As shown, the abutting surface 23 of the second furniture component 20 is configured to be arranged inside the abutting surface 13 and abut against the abutting surface 13 on the interior of the tubular portion 10a. The tubular portion 10a extends in the longitudinal direction such that the open end 10c of the tubular portion 10a abuts against the first side portion 21a of the wall 21, thereby covering these portions of the connecting device inside the tubular portion 10a.

[0155] like Figures 2c to 2e As shown, the tenon 11 is partially positioned in the open end 10c of the tubular member 10, such that the tenon 11 extends partially inside the tubular member 10 and extends partially beyond the open end 10c of the tubular member 10 in the longitudinal direction L.

[0156] The tenon 11 is a separate element attached to the first furniture component 10. For example... Figures 2c to 2e As disclosed, the tenon 11 can be attached to the first furniture component 10, for example, by means of an attachment portion 11d, which is positioned to extend further into the tubular member 10 than the base portion 11a.

[0157] In this embodiment, the base portion 11a may form an abutting surface that abuts against the inner surface 22a of the through opening 22 when the tenon 11 is inserted through the through opening 22 of the wall 21.

[0158] exist Figures 5a to 5b , Figure 6 and Figures 7a to 7b In the middle, it was made public Figures 2a to 2e Alternative embodiments of the embodiments shown are described. In this embodiment, for example, such as... Figure 5a and Figure 7a As indicated, the abutting surface 13 of the first furniture component 10 is formed by the end surface of the tubular member 10. For example... Figure 5a As indicated in the diagram, the abutting surface 23 of the second component 20 is formed by the outer surface 23 of the wall 21 (or alternatively, the first side 21a).

[0159] The tenon 11 is formed from a plate-shaped metal piece, which is essentially shaped as a longitudinally extending member with a U-shaped cross-section. The tenon 11 is oriented with its continuously curved bottom end facing the connecting member 30. The legs of the U-shaped cross-section extend parallel to the insertion direction B, in which the connecting member 30 is inserted into the second furniture component 20. When viewed along the longitudinal direction L, the tenon 11 has an attachment portion 11d, a base portion 11a, and a plurality of alternately arranged ridges 11c and valleys 11b. The attachment portion 11d is inserted into the tubular member 10 and is attached to the interior of the tubular member 10, for example, by welding.

[0160] If possible Figures 5a to 5b Note that there are no longitudinally extending abutment surfaces 13, 23 in this embodiment. However, in this embodiment, the base portion 11a forming the abutment surface provides a locking effect to prevent relative lateral movement of the first furniture component 10 and the second furniture component 20. When the tenon 11 is inserted into the through opening 22 through the wall 21, the abutment surface abuts against the inner surface or edge surface 22a of the through opening 22. The curved, continuous bottom end of the U-shaped cross-section abuts against the edge surface 22a with a consistent shape. The free ends of the legs of the U-shaped cross-section of the tenon 11 abut against two abutment surfaces formed in the through opening 22, which face in the opposite direction to the insertion direction B, along which the connecting member 30 is inserted into the second furniture component 20. As long as the above-mentioned abutment surfaces are provided, the shape of the through opening can be shaped differently from the cross-sectional shape of the tenon 11.

[0161] Reference Figures 3a to 3g A connection device for connecting a third furniture component 40 to a second furniture component 20 is disclosed.

[0162] The third furniture component 40 is tubular and has a main extension along the longitudinal direction L. For example... Figure 3d As shown, the third furniture component 40 has an open end 41 facing the longitudinal direction L.

[0163] like Figures 3a to 3c As shown, the second furniture component 20 is configured to receive a tenon 51. In the attached position, the tenon 51 extends from the second furniture component 20 along a direction L' opposite to the longitudinal direction L toward its free end 51c. For example, as... Figure 3a As shown, the tenon 51 has two ridges 51b, and when viewed along the longitudinal direction L, each ridge 51b is followed by a valley 51a.

[0164] like Figure 3d As shown, the connecting device also includes a connecting member 60 configured to insert through the open end 41 and into the third furniture component 40. The connecting member 60 has a recess 31 designed substantially in the same manner as the recess 31 of the connecting member 30. The recess 31 of the connecting member 60 has a locking portion 31b configured to receive the tenon 51 by relative movement between the third furniture component 40 and the connecting member 60 in a direction T transverse to the longitudinal direction L, and the locking portion 31b is configured to interact with the valley 51a of the tenon 51 to prevent the tenon 51 from being removed from the locking portion 31b along the longitudinal direction L.

[0165] The second furniture component 20 and the third furniture component 40 are configured to be connected to each other by the following:

[0166] like Figure 3d As shown, the connecting member 60 is at least partially inserted into the third furniture component 40, and

[0167] like Figure 3e As shown, the third furniture component 40 with connecting member 60 is moved relative to the tenon 51 in the travel direction B along the transverse direction T, such that the tenon 51 slides into the locking portion 31b of the connecting member 60.

[0168] exist Figure 3f The image shows a second furniture component 20 and a third furniture component 40 in a connected state. It can be noted that the connecting device is covered by a cover plate 51d on the tubular furniture component 40 and the tenon 51.

[0169] The following will mainly refer to Figures 3a to 3cThe tenon 51 is disclosed in more detail. As described above, the tenon 51 is configured to attach to the tubular furniture component 20 and to provide part of a connection device between the tubular furniture component 20 and the third furniture component 40. The tenon 51 briefly includes a connecting portion 51' and an attaching portion 51'.

[0170] The connecting portion 51' has the two ridges 51b described above, and when viewed along the longitudinal direction L, each ridge 51b is followed by a valley 51a. The connecting portion 51' is configured to extend from the second furniture component 20 along a direction L' opposite to the longitudinal direction L toward the free end 51c of the tenon 51.

[0171] The attachment portion 51” has a neck portion 52, which, when viewed along the longitudinal direction L, is followed by a head portion 53. The head portion 53 has an extension in a first transverse direction T’ that is larger than the extension of the neck portion 52 along the first transverse direction T’, and larger than both the extensions of the head portion 53 and the neck portion 52 along the second transverse direction T”, which is orthogonal to the first transverse direction T’.

[0172] like Figure 3a As shown, the second furniture component 20 is provided with an elongated through-hole 25 extending through the first wall 21 of the tubular furniture component 20. The elongated through-hole 25 has a width W along its longitudinal extension in the transverse direction T25 (see Figure 25). Figure 3g The width W is greater than the extensions of the head portion 53 and the neck portion 52 along the second lateral direction T”, and smaller than the extension of the head portion 53 along the first lateral direction T’.

[0173] Tenon 51 is configured to be attached to tubular furniture component 20 by means of:

[0174] The attachment portion 51” is inserted along F into the elongated through opening 25, wherein the tenon 51 is oriented during insertion with the first transverse direction T' aligned with the longitudinal direction L25 of the elongated through opening 25, or with the first transverse direction T' having at least a major component along the longitudinal direction L25 of the elongated through opening 25, such that the head portion 53 passes through the elongated through opening 25, and thereafter…

[0175] like Figure 3b As shown, the tenon 51 is rotated along the first direction H about the axis G extending along the longitudinal direction L, such that the head portion 53 interacts with the inner side portion 21b of the wall 21, thereby preventing the head portion 53 from being pulled out of the elongated through opening 25.

[0176] exist Figure 3c The tenon 51 is shown in its attachment position.

[0177] like Figure 3a As shown in the cross-section AA, when viewed along the first transverse direction T', the two ends 52a, 52b of the neck portion 52 have:

[0178] The rotating blocking corner portion 52a” is configured to interact with the edge of the elongated through opening 25, thereby preventing the tenon 51 from rotating about the axis G in a second direction opposite to the first direction H.

[0179] The rotation allows the corner portion 52a' to be configured to pass along the edge of the elongated through opening 25, thereby allowing the tenon 51 to rotate about the axis G in the first direction H.

[0180] Thus, the tenon 51 can be rotated from its orientation when inserted to a desired orientation that prevents further rotation of the tenon 51.

[0181] Two rotating blocking corner portions 52a” and 52b” are arranged diagonally opposite each other, and two rotating allowable corner portions 52a’ and 52b’ are arranged diagonally opposite each other.

[0182] The head portion 53 may be asymmetrical in design and the elongated through opening 25 may be asymmetrical in design, such that the head portion 53 of the tenon 51 can only be inserted in one of two opposite orientations in the first transverse direction T': in which orientation the first transverse direction T' is aligned with the longitudinal direction L25 of the elongated through opening 25 or has a major component along the longitudinal direction L25 of the elongated through opening 25.

[0183] exist Figure 3a and Figure 3g The diagram shows a head portion 53 with a relatively sharp corner at one end portion 53a and a relatively rounded corner at the other end portion 53b. Similarly, an elongated through opening 25 has a relatively sharp corner at one end portion 25a and a relatively rounded corner at the other end portion 25b. The radius of the corners is chosen such that the head portion 53 can only be inserted into the elongated through opening 25 with the relatively sharp corner at the end portion 53a facing the relatively sharp corner of the elongated through opening 25.

[0184] Therefore, it can be controlled that the tenon 51 can only be inserted in the orientation that results in the expected orientation of the tenon 51 when it is combined with the rotation blocking corners 52a”, 52b” and the rotation allowing corners 52a’, 52b’.

[0185] exist Figure 8 In the alternative embodiment shown, the elongated through opening 125 may extend along the extension of the second furniture component 20. In other words, the aforementioned first lateral direction T' and second lateral direction T” will be reversed. In this alternative embodiment, the rotation-blocking corner of the neck portion is omitted, and instead, rotation-blocking corners 153a” and 153b” at the ends 153a and 153b of the head portion 153 are used to block rotation. The rotation-blocking corners 153a” and 153b” engage with the inner wall of the second furniture component 20 to prevent further rotation of the tenon 51. Thus, the edge at the elongated opening is not required to prevent rotation. Furthermore, the head portion 153 includes rotation-allowing corners 153a’ and 153b’, which are configured to allow the tenon 51 to engage with the reference tenon 51. Figure 3b The same manner is used to rotate along the first direction H.

[0186] In a preferred embodiment, the present invention is conceived in furniture comprising a first furniture component 10, a second furniture component 20, and a third furniture component 40, wherein, as disclosed above in its most general terms or in the preferred embodiment, the first furniture component 10 and the second furniture component 20 are connected to each other by a connecting means for connecting the first furniture component 10 to the second furniture component 20, and wherein, as disclosed above in its most general terms or in the preferred embodiment, the second furniture component 20 and the third furniture component 40 are connected to each other by a connecting means for connecting the second furniture component 20 to the third furniture component 40.

[0187] exist Figures 4a to 4c The image shows a similar structure between the first furniture component 10 and the second furniture component 20. Figures 2a to 2e The connection device of the connection device. However, instead of using Figure 1 The connecting member 30, in which the connecting device uses a connecting member 80 capable of being inserted into or forming part of the tubular member 70. The tubular member 70 is intended to extend as a continuation of the second furniture component 20. This design is suitable, for example, for providing legs 70 at the bottom of the furniture. The connecting member 80 is provided with reference... Figure 1 The recess 31 is disclosed in detail.

[0188] It is also conceivable that in a design where a connecting member 80 or a receiving connecting member 80 is provided at one end of the furniture component 70, and a through opening 22 and an abutment surface 23 are provided at the other end of the furniture component 70, Figure 1 and Figures 2a to 2e Connection device and Figures 4a to 4c The connecting devices are combined. With this design, multiple furniture parts 70 can be stacked on top of each other, and each furniture part 70 is connected to a first furniture part 10 at each such interconnection. At the top of this stack, the connecting devices can be arranged as follows: Figure 1 and Figures 2a to 2e The connecting device disclosed herein ends, and at the bottom of this stack, the connecting device can be connected as follows: Figures 4a to 4c The connection device disclosed in the document has ended.

[0189] It can be noted that the figures shown in the various figures are as follows Figures 4a to 4c The furniture with the connecting device shown can alternatively be connected at both ends of the second furniture component 20. Figure 1 and Figures 2a to 2e The connection device disclosed in the document ends here.

[0190] It is conceivable that many modifications may be made to the embodiments described herein, and these modifications are still within the scope of the invention as defined by the appended claims.

[0191] One or more abutting surfaces 13 may be, for example, multiple separate abutting surfaces, each abutting surface extending from the first side 21a of the wall 21 in a direction L' opposite to the longitudinal direction L, and distributed circumferentially C relative to each other around the tenon 11.

[0192] One or more abutting surfaces 13 may be, for example, multiple separate abutting surfaces, each abutting surface extending from the first side 21a of the wall 21 in a direction L' opposite to the longitudinal direction L, and distributed circumferentially C relative to each other around the through opening 22.

[0193] It is noteworthy that, in the preferred embodiment, the various furniture components 10, 20, and 40 are formed from square or rectangular tubes. However, furniture components do not necessarily have to be formed from tubes. Furniture components can be solid components with recesses or openings that provide the necessary spaces or cavities for receiving tenons, connecting members, etc., provided by the interior of the tube in the preferred embodiment. It is also noteworthy that the shape of the tubular or solid component does not necessarily have to be square or rectangular. Other shapes are also conceivable, such as other types of polygons, circles, ellipses, and ellipsoids.

[0194] As mentioned above, it can be noted that the furniture components described can refer to different types of furniture. For example, furniture components may refer to individual freestanding furniture, such as shelves, bookshelves, TV cabinets, side panels, tables, and cupboards. Furniture components may also refer to built-in cabinets or shelves, such as wall-mounted kitchen cabinets and wall-mounted kitchen shelves. Furniture components may also refer to semi-built-in cabinets or shelves, such as wall-mounted TV cabinets. Whether furniture components are built-in or freestanding, they may refer not only to furniture designed for storage, such as cabinets and shelves, but also to furniture components used for other types of purposes. Furniture components may, for example, refer to furniture for sitting, such as sofas, benches, and chairs.
