Description

Technical Field

[0001] The present invention relates to a furniture module comprising two opposing side walls interconnected by a rear wall panel arrangement and a shelf configured to be positioned between the side walls, preferably between respective top portions of the side walls.

[0002] The invention also relates to a method of attaching a shelf between two opposing side walls of a furniture module, wherein the two opposing side walls are interconnected by a flexible rear wall panel arrangement. Background Art

[0003] Although it is convenient and cost-effective to transport furniture modules in an unassembled state and then assemble them at the site of their intended use, some furniture modules, such as wardrobes, are difficult to assemble at home due to their size. For example, it is often difficult for one person to assemble a wardrobe, and it is particularly difficult when the available space is limited, and the wardrobe needs to be placed in an upright position from the beginning to perform the assembly. The need to assemble the wardrobe in an upright position may be related to the following problems, for example: lack of floor space, and / or due to the fact that a greater ceiling height is required when lifting the wardrobe from a laid-down position to an upright position than the ceiling height required when it is placed upright, and the ceiling lacks the additional clearance required by the above-mentioned fact.

[0004] WO 2018 / 004416 A1 discloses a furniture module in which these problems are solved. It discloses a furniture module comprising two opposing side walls, which are connected to each other via a back panel pre-mounted to the two side walls. The back panel can be folded relative to the two side walls and / or is formed by at least two parts that can be folded relative to each other.

[0005] However, as will be apparent, there is still room for improvement in facilitating assembly and still providing a sturdy furniture module. Summary of the invention

[0006] The object of the present invention is to provide a furniture module which is strong and easy to assemble.

[0007] This object has been achieved by a furniture module comprising:

[0008] two opposite side walls, the two opposite side walls being connected to each other by a rear wall panel assembly,

[0009] a shelf configured to be positioned between the side walls, preferably between respective top portions of the side walls,

[0010] wherein the shelf is provided with a front pin on each side of the shelf and a central pin on each side of the shelf,

[0011] wherein the front pin on each side of the shelf extends a first distance from the respective side of the shelf to the respective free end of the respective pin, and the central pin on each side of the shelf extends a second distance from the respective side of the shelf to the respective free end of the respective pin, wherein the first distance is greater than the second distance. The front pin and the central pin are each configured for insertion into an associated front recess and a central recess of a respective portion of the side wall.

[0012] This design makes it possible to make good use of the space provided between the opposite side walls when the opposite side walls are in the shelf mounting position, in which the horizontal distance between the front portions of the side walls is greater than the horizontal distance between the rear portions of the side walls. The front pin can be relatively long and thus provide a secure connection to the side walls without the central pin forcing the side walls to be too far apart. The first distance that the front pin extends from each side of the shelf can preferably be associated with a second distance that the central pin extends from each side of the shelf, which is associated with a corresponding distance from the rear wall panel device, so that both the front pin and the central pin abut against and slide against the corresponding inwardly facing main surface.

[0013] It may be noted that the shelf may also be referred to as the top or top panel of a furniture module, such as the top or top panel of a wardrobe, especially when the shelf is mounted between the corresponding top parts of the side walls. If there is space above the furniture module, the top panel may also be used as a shelf in the sense that it allows items to be stored on top of the furniture module. If the shelf is mounted in the lower part of the furniture module, the shelf may also be referred to as the bottom or bottom panel.

[0014] Preferred embodiments are presented in the dependent claims and the description.

[0015] In one embodiment, the front and central pins are each configured for insertion into associated front and central recesses of respective top portions of the side walls.

[0016] The rear wall panel arrangement is preferably flexible. In this context, "flexible" preferably means that the rear wall panel arrangement is configured to allow the two opposing side walls to be folded relative to each other and to assume a lay-flat condition.

[0017] Preferably, each of the opposing side walls comprises a front recess and a central recess, which are formed on the main surface facing inwardly facing the opposing side wall and are respectively positioned in the front portion and the central portion of the corresponding side wall, preferably respectively positioned in the front top portion and the central top portion of the corresponding side wall.

[0018] Preferably, the front recess and the central recess each include an insertion portion and a locking portion extending from the insertion portion in a sliding direction of the shelf.

[0019] Preferably, the flexible rear wall panel device is configured to allow the relative side walls to be in a shelf installation position, in which the horizontal distance between the front portions of the side walls is greater than the horizontal distance between the rear portions of the side walls, thereby allowing the shelf to be inserted in the following manner: the shelf is at least partially moved along the shelf sliding direction until the pin reaches the corresponding associated recess, and after the corresponding pin is inserted into the insertion portion of the corresponding recess, the shelf is further moved along the shelf sliding direction so that the corresponding pin is transferred to the locking portion of the corresponding recess.

[0020] Since the front recess and the central recess each include an insertion portion and a locking portion extending from the insertion portion along the shelf sliding direction, and in combination with a flexible rear wall panel device configured to allow the opposite side walls to be in a shelf mounting position, in which the horizontal distance between the front portions of the side walls is greater than the horizontal distance between the rear portions of the side walls, the shelf can be inserted in the following manner: the shelf moves along the shelf sliding direction until the pin reaches the corresponding associated recess, and after the corresponding pin is inserted into the insertion portion of the corresponding recess, it is further moved along the shelf sliding direction so that the corresponding pin is transferred to the locking portion of the corresponding recess. This allows the furniture module to be installed in place even when there is no space above the furniture module. In addition, by configuring the flexible rear wall panel device to allow the opposite side walls to be in a shelf mounting position, the shelf can be inserted between the opposite side walls and pushed backwards, wherein, in the shelf mounting position, the horizontal distance between the front portions of the side walls is greater than the horizontal distance between the rear portions of the side walls. This backward movement of the shelf can be used to provide a slightly outwardly open position of the side wall in the installation position or further expand the slightly outwardly open position of the side wall. The provision of the open position or the further expansion of the open position may resist the elasticity of the partially assembled furniture module, that is, the inherent tension of the partially assembled furniture module, so that the relative side wall moves inward from the installation position toward the expected final position. This elasticity can be used to more or less automatically insert the corresponding pin into the insertion part of the corresponding recess by the side wall automatically moving toward each other due to elasticity when the pin reaches the corresponding associated recess during the insertion movement of the shelf. Therefore, there is no need to actively push the corresponding side wall inward to provide the desired insertion of the corresponding pin into the corresponding recess. Therefore, the conceptual design of the furniture module makes it possible to install the furniture module without requiring any additional space above the furniture module. In addition, the conceptual design can actually design the furniture so that the furniture becomes elastic, so that the corresponding pin is automatically inserted into the corresponding recess.

[0021] The portion of a label associated with a horizontal position, such as a label having any one of the front / center / rear labels, and a label associated with a vertical position, such as a label having any one of the top / center / lower labels, refers to a portion based on the label being restricted in both the vertical and horizontal directions. For example, the front lower corner portion preferably refers to a portion at the front lower corner and within a certain distance measured in any direction from the front lower corner, which is approximately 25% of the distance from the front lower corner to the rear lower corner of the corresponding side wall. This preferably also applies to other portions of labels associated with a horizontal position and labels associated with a vertical position. When referring to a portion indicated as being central along the horizontal direction, whether it is part of a single label or part of a double label, it preferably refers to a portion having such a horizontal extension, which is approximately 25% of the shortest distance from the front to the rear of the corresponding side wall and is positioned in the center around the roughly vertical centerline between the front and the rear. Thus, a portion referred to simply as central in the context of a horizontal position preferably refers to a portion extending vertically, which is centered on the center line between the front and the rear and has an extension of approximately 25% of the shortest distance from the front to the rear of the respective side wall. A portion referred to as centered and also labeled with top or bottom is preferably also limited from the top or bottom, respectively, so that the portion in the vertical direction has an extension of approximately 25% of the shortest distance from the front to the rear. It can also be noted that the label can be directly associated with the respective entity or can be derived via a label associated with a base entity or with a second entity, which interacts with the first entity. For example, a central pin on a shelf preferably positioned between the respective top portions of the side walls can in a sense be said to be located in a portion having a derived label of central in the horizontal direction and top in the vertical direction, i.e. it can also be referred to as a central top portion of the furniture module.

[0022] In a preferred embodiment, the respective insertion portion of each recess has an insertion portion width measured in a direction transverse to the depth direction and transverse to the shelf sliding direction.

[0023] The respective first locking portion and the respective second locking portion of each recess may each have opposite recess side walls facing each other and preferably each having an extension in the depth direction and in the shelf sliding direction.

[0024] The opposing recess side walls may be provided with one or more opposing ridges. Each ridge preferably has a longitudinal extension along the shelf sliding direction and a height extending from the corresponding recess side wall towards the opposing ridge of the opposing recess side wall.

[0025] The opposing recess side walls may each be provided with at least one set of opposing valleys positioned at a valley depth greater than the ridge depth,

[0026] Preferably, the locking portion width formed by the shortest distance between the opposing ridges is smaller than the insertion portion width, and smaller than the shortest distance between the opposing valleys.

[0027] In a preferred embodiment, as seen along the longitudinal extension of the respective pin extending from the respective side of the shelf to the respective free end of the respective pin, each pin comprises a stem having a stem width followed by at least one pin ridge. The pin ridge preferably has an extension extending in the radial direction of the respective pin and along at least a portion of the circumference of the respective pin. "Following" is intended to mean that the at least one pin ridge is positioned at a greater distance from the respective side of the shelf. In this case, it can be noted that in the case where the respective pin is provided with more than one pin ridge, the portion between the two pin ridges may also be referred to as a valley. In the disclosed embodiment, as seen along the longitudinal extension of the respective pin, the front pins each comprise a first stem or valley, a first ridge, a second stem or valley, and a second ridge near the free end of the pin. In a preferred embodiment, the respective central pin comprises a stem and a ridge.

[0028] Preferably, the stems or valleys, ridges and front and central recesses of the front and central pins, respectively, are of the same rounded triangular shape and size, and the difference in length of the front and central pins and the corresponding difference in depth of the recesses is provided by having different numbers of ridges and valleys. This facilitates manufacturing.

[0029] The shank of the corresponding pin is configured to pass between two opposing ridges of the corresponding recess when the corresponding pin is transferred from the corresponding insertion portion to the corresponding locking portion, so that the corresponding pin ridge now positioned at a greater depth is caught under the two opposing ridges of the corresponding recess.

[0030] The furniture module may also include at least one shelf locking member, each having a body portion configured to be attached to the side wall and a pin connected to the respective body portion, the pin being configured to interact with a recess formed in a downwardly facing major surface of the shelf and thereby prevent the shelf from being removed from the intended installation position of the shelf. By providing a locking member, accidental removal of the shelf is prevented or at least there is some reaction to the accidental removal of the shelf.

[0031] The pin is preferably connected to the corresponding body part in a movably manner and can be moved between a shelf insertion position and a shelf locking position, in which the shelf can be inserted between the side walls to reach the expected installation position of the shelf, and in the shelf locking position, the pin interacts with a recess formed in the downward-facing main surface of the shelf and thus prevents the shelf from being removed from the expected installation position of the shelf. The shelf locking member can be designed so that the pin is moved from the shelf insertion position to the shelf locking position by the active action of the installer. The shelf locking member can be designed so that when the shelf reaches its expected installation position, the pin automatically moves from the shelf insertion position to the shelf locking position. The latter can be achieved, for example, by arranging a resilient connection between the pin and the body part.

[0032] Preferably, the furniture module comprises at least two shelf locking members, each of which is configured to be attached to a respective one of the two opposing side walls.

[0033] Furniture modules can also include:

[0034] a first member configured to be attached to at least one of the side walls, and

[0035] a second member configured to be attached to at least one of the side walls, preferably to two opposing side walls,

[0036] wherein the corresponding side wall comprises a first recess,

[0037] wherein the first recess includes an insertion portion, a first locking portion extending from the insertion portion along a first direction, and a second locking portion extending from the insertion portion along a second direction, the second direction being different from the first direction, and

[0038] wherein the first recess is configured to receive a first pin of the first component and a first pin of the second component,

[0039] The projection distance between the first locking portion and the second locking portion measured along the first direction is such that during installation, the second component prevents the first component from moving in a direction opposite to the first direction and being released.

[0040] In addition, the first member can be basically any part of the furniture. The first member can be, for example, a height adjustment member arranged at the rear lower corner of the furniture module. The first member can be, for example, a furniture piece extending between two opposite sides of the furniture module, such as a furniture piece extending between two opposite side walls of the furniture module. Therefore, the first member can be, for example, a bottom shelf, a central shelf or a top shelf of the furniture module. It can also be noted that the furniture member can be provided with one or more recesses, the one or more recesses being formed with an insertion portion and two locking portions, and combined with one or more recesses being formed with an insertion portion and a locking portion. For example, it is conceivable that a shelf, such as a shelf forming the bottom or top of a wardrobe, is connected to the side wall by a rear pin and / or a central pin inserted into a corresponding recess having only one locking portion, and wherein the front pin is inserted into a recess having two locking portions, wherein the second locking portion is configured to receive the first pin of the front frame member so that the front frame member abuts the shelf and prevents the shelf from being removed. In this case, the front frame member may also similarly have a second pin configured to be received by another recess also having an insertion portion and a locking portion.

[0041] In the following, the present invention will be discussed mainly with reference to a preferred embodiment, in which there are provided: two furniture components, which form two opposite side walls, which are preferably connected to each other by a rear wall panel device; two first components, which form a first height adjustment component and a second height adjustment component, which are configured to be attached to the respective opposite side walls at the front lower corner portion of the respective side walls on their main surfaces facing inwards towards the opposite side walls; and a second component, which forms a lower front frame component, which is configured to be attached to the two opposite side walls at the respective front lower corner portions of the respective side walls on their main surfaces facing inwards towards the opposite side walls, and thus connect the two opposite side walls to each other at the front lower portion of the furniture module.

[0042] Preferably, the respective side wall further comprises a second recess, wherein the respective first recess on the respective side wall panel is positioned at a first height and the respective second recess on the respective side wall panel is positioned at a second height, wherein the first height is preferably greater than the second height.

[0043] Preferably, the recesses are positioned such that a projection of a corresponding first recess on a horizontal plane at least partially overlaps a projection of a corresponding second recess on the horizontal plane.

[0044] More preferably, the recesses are positioned such that a geometric line extending from a center point of a respective insertion portion of a respective first recess to a center point of a respective insertion portion of a respective second recess extends substantially vertically downward.

[0045] By having recesses at different heights, the force generated by gravity can be used to keep the height adjustment member and / or the lower front frame member in the desired position. This effect is further improved in the case of horizontal overlap, and even further improved in the case where a recess is located more or less above another recess.

[0046] Preferably, the first direction is substantially horizontal and the second direction is different from the corresponding first direction. Thus, the height adjustment member can be installed in a state where the height adjustment member has a preset length substantially corresponding to the expected non-adjustment position. This makes it possible to design a height adjustment member with a relatively limited adjustment stroke length, because the full adjustment stroke length can be used to actually provide adjustment of the height adjustment member.

[0047] Alternatively or in addition, preferably, the second direction is substantially vertical and the first direction is different from the corresponding second direction. This makes it possible to utilize the force generated by gravity to maintain the lower front frame member in the desired position. Furthermore, since the lower front frame member can be maintained in the desired position with the help of gravity, the height adjustment member connected to the same recess can in turn be maintained in the desired position with the help of the lower frame member.

[0048] Preferably, the first direction is substantially horizontal and the second direction is substantially vertical.

[0049] It can be noted that, although in a preferred embodiment, the first direction is substantially horizontal, and wherein the second direction is substantially vertical, other combinations of directions are also conceivable. The second direction can be, for example, substantially vertical, and the first direction combined therewith is different from the second direction and also from the horizontal direction. The first direction can, for example, extend from an insertion portion that is inclined upward and backward. It can also be noted that, although in a preferred embodiment, the first direction of the first recess is parallel to the second direction of the second recess, it is conceivable that the two directions are different from each other. For example, it is conceivable that the first direction of the first recess, i.e. the first direction of the upper recess of the two recesses, extends upward and backward obliquely, and the first direction of the second recess combined therewith, i.e. the first direction of the lower recess, extends horizontally or at least more horizontally. It can also be noted that the first direction can be, for example, substantially horizontal, and the second direction combined therewith is different from the first direction and also from the vertical direction. The second direction can, for example, be inclined downward and backward, so that when the lower front frame member is installed, the lower front frame member moves backward toward the corresponding height adjustment member.

[0050] Preferably, the furniture module includes two first components, which form a first height adjustment component and a second height adjustment component, and the first height adjustment component and the second height adjustment component are configured to be attached to the corresponding opposite side wall at the front lower corner portion of the corresponding side wall on the inward-facing main surface of the corresponding side wall facing the opposite side wall.

[0051] The furniture module can also be configured so that the second member forms a lower front frame member, which is configured to be attached to the two opposite side walls at the corresponding front lower corner portions of the corresponding side walls on the inward-facing main surfaces of the corresponding side walls facing the opposite side walls, and thus connect the two opposite side walls to each other at the front lower portion of the furniture module.

[0052] Each of the opposing side walls may include a first recess and a second recess formed on an inwardly facing major surface facing the opposing side wall and positioned at a front lower corner portion of the corresponding side wall.

[0053] The corresponding recesses at the front lower corner portion may each include an insertion portion, a first locking portion extending from the insertion portion along a corresponding first direction, and a second locking portion extending from the insertion portion along a corresponding second direction, the corresponding second direction being different from the corresponding first direction.

[0054] At the front lower corner portion of the corresponding side wall panel, the first recess of the first side wall can be configured to receive the first pin of the first height adjustment member and the first pin on the first side portion of the lower front frame member, the second recess of the first side wall can be configured to receive the second pin of the first height adjustment member and the second pin on the first side portion of the lower front frame member, the first recess of the second side wall can be configured to receive the first pin of the second height adjustment member and the first pin on the second side portion of the lower front frame member, and the second recess of the second side wall can be configured to receive the second pin of the second height adjustment member and the second pin on the second side portion of the lower front frame member.

[0055] By designing the individual recesses so that they are each provided with an insertion portion, a first locking portion extending from the insertion portion in a respective first direction, and a second locking portion extending from the insertion portion in a respective second direction, the respective second direction being different from the respective first direction, it helps to provide a compact design, wherein the lower front frame member and the first and second height adjustment members are positioned close to each other and a machining operation such as a milling operation can still be performed to provide the recesses in a single operation. This manufacturing can be performed, for example, by allowing a milling tool to form the insertion portion, and then moving the milling tool to form the first locking portion, followed by moving the milling tool to form the second locking portion, and then returning the milling tool to the insertion portion and being removed from the respective recess. Preferably, the profile of the milling tool in the depth direction of the recess is similar to the profile of a pin intended to be inserted into the recess. By designing the recesses so that they are each provided with an insertion portion, a first locking portion extending from the insertion portion in a respective first direction, and a second locking portion extending from the insertion portion in a respective second direction, the respective second direction being different from the respective first direction, it is helpful to provide an interlocking function, i.e. the height adjustment member can be automatically maintained in the desired position, because the lower front frame member subsequently connected to the recess can be used to prevent the height adjustment member from being removed from the respective recess. This possibility of providing an interlocking function can in turn be used to provide a first direction in a direction that is beneficial from a load-bearing perspective and a height adjustment perspective, but which may not be truly beneficial from the perspective of preventing the height adjustment member from being removed from the respective recess. In a preferred embodiment, this is used to provide a first direction in a substantially horizontal direction.

[0056] With the design described above, the installer can conveniently simply position the height adjustment member at the desired location and then simply install the lower front frame member to achieve a secure interconnection of the two opposing side walls at the lower front portion of the furniture module.

[0057] The pin of the lower front frame member may be configured to be respectively inserted into the first recess, the insertion portion of the second recess at the corresponding front lower corner portion, and transferred to the first locking portion of the corresponding recess.

[0058] In a preferred embodiment, the pin of the corresponding height adjustment member is configured to be inserted into the insertion portion of the corresponding recess and transferred to the first locking portion of the corresponding recess before the pin of the lower front frame member is configured to be inserted into the insertion portion of the corresponding recess and transferred to the second locking portion of the corresponding recess.

[0059] The projected distance between the first locking portion and the second locking portion measured along the first direction can be such that when installed, the corresponding height adjustment member abuts the lower front frame member, thereby preventing the corresponding height adjustment member from being released by the lower front frame member from moving in a direction opposite to the first direction. In order to achieve this, the projected distance between the first locking portion and the second locking portion is preferably related to the physical design of the first member and the second member, so that the first member and the second member together occupy at least a part of the projected distance, so that the first member contacts the second member before the first member reaches the insertion portion. Preferably, the first member and the second member together occupy the entire projected distance, so that when the pins of the corresponding members are in the first locking portion or the second locking portion, respectively, the corresponding members have abutted each other. It can be noted that the projected distance between the first locking portion and the second locking portion can be at a first position along the second direction, and the first member and the second member can contact or abut each other at a second position different from the first position along the second direction. In this case, it can also be noted that the engagement between the first member and the second member is preferably such that the first member and the second member can slide along each other, thereby allowing the second member to move along the second direction while in contact with the first member.

[0060] In this sense, "abutment" may mean that the height adjustment member and the lower front frame member respectively exert forces opposite to each other in the first direction. By this design, the respective height adjustment member remains in the respective intended position, since any movement of the height adjustment member is prevented as long as the lower front frame member remains in its intended position. This is preferably combined with the fact that the second direction is substantially vertical.

[0061] In a preferred embodiment, the respective insertion portion of each recess has an insertion portion width measured in a direction transverse to the depth direction and measured transverse to the first direction and measured transverse to the second direction.

[0062] The respective first locking portion and the respective second locking portion of each recess may each have opposing recess side walls facing each other and each having an extension in the depth direction and in the first direction or the second direction, respectively.

[0063] Each of the opposing side walls may be provided with:

[0064] at least one ridge, wherein each ridge is located at a ridge depth viewed in the depth direction and has a longitudinal extension in the shelf sliding direction and a height extending from the respective side wall toward the opposite ridge of the opposite side wall, and

[0065] At least one valley is positioned at a valley depth, the valley depth being greater than the ridge depth.

[0066] The locking portion width formed with the shortest distance between the opposing ridges may be smaller than the insertion portion width, and smaller than the shortest distance between the opposing valleys.

[0067] By this design, a secure interconnection is provided between the pins of the first and second height adjustment members and the pins of the lower front frame member on the one hand, and the recess provides a solid furniture module on the other hand. The ridges and valleys prevent the pins of the first and second height adjustment members and the pins of the lower front frame member from being pulled out of the recess.

[0068] In a preferred embodiment, as seen along the longitudinal extension of the corresponding pin extending from the corresponding height adjustment member, the lower front frame member to the corresponding free end of the corresponding pin, each pin of the first height adjustment member and the second height adjustment member and / or each pin of the lower front frame member includes a stem portion having a stem width, followed by at least one pin ridge, the pin ridge having an extension extending in the radial direction of the corresponding pin and along at least a portion of the circumference of the corresponding pin.

[0069] In this case, it can be noted that the depth of all recesses configured to receive the pins of the respective parts is preferably less than the material thickness of the part forming these recesses, i.e. the recesses are preferably not visible on the surface opposite to the surface in which the respective recess is formed.

[0070] The objects described above are also achieved by a method of attaching a shelf between two opposite side walls of a furniture module, the two opposite side walls being interconnected by a rear wall panel arrangement, preferably a flexible rear wall panel arrangement, the method comprising:

[0071] The shelf is attached between two opposite side walls, preferably between the corresponding top parts of the corresponding side walls, in the following manner: the rear wall panel device allows the opposite side walls to be in a shelf installation position, in which the horizontal distance between the front parts of the side walls is greater than the horizontal distance between the rear parts of the side walls; and the shelf is moved along the shelf sliding direction until the front pin on each side of the shelf and the central pin on each side of the shelf reach the corresponding associated recesses, and after the corresponding pins are inserted into the insertion parts of the corresponding recesses, the shelf is further moved along the shelf sliding direction so that the corresponding pins are transferred to the locking parts of the corresponding recesses.

[0072] The advantages achieved by the various features have been explained above with reference to the furniture module, and these advantages are equally applicable to the method. The preferred embodiments of the various components and features discussed with reference to the furniture module are equally applicable to the method.

[0073] The method may further include:

[0074] The first height adjustment member and the second height adjustment member are attached to the front lower corner portion of the corresponding side wall on the inwardly facing main surface of the corresponding side wall facing the opposite side wall by inserting the first pin and the second pin of the corresponding height adjustment member into the inserting portion of the first recess and the second recess formed at the corresponding front lower corner portion of the corresponding side wall, and by sliding the corresponding height adjustment member in a first direction so that the pins of the corresponding height adjustment member are transferred to the corresponding first locking portion of the corresponding recess, and

[0075] The lower front frame member is attached to the two opposite side walls by inserting the first pin and the second pin on the first side portion of the lower front frame member and the first pin and the second pin on the second side portion of the lower front frame member into corresponding insertion portions of the first recess and the second recess formed in the corresponding lower front corner portions of the corresponding side walls, and sliding the lower front frame member in a second direction different from the first direction so that the pins of the lower front frame member are transferred to the corresponding second locking portions of the corresponding recesses,

[0076] Wherein, preferably, before the action of attaching the shelf to the two opposite side walls, the action of attaching the first height adjustment member and the second height adjustment member to the two opposite side walls and the action of attaching the lower front frame member to the two opposite side walls are performed.

[0077] By attaching the first height adjustment member and the second height adjustment member to two opposing side walls, and attaching the lower front frame member to the two opposing side walls, the desired distance between the side walls at the front lower portion is maintained when the shelf is to be installed. This is advantageous because maintaining the distance between the side walls at the front lower portion causes the pins on the shelf to force the top portions of the side walls apart, which in turn causes the side walls to move toward each other when the pins of the shelf reach the associated recesses of the side walls, and the pins will therefore be inserted into the associated recesses.

[0078] Preferably, the act of sliding the respective height adjustment member in the first direction involves sliding the respective height adjustment member in a substantially horizontal direction.

[0079] Preferably, the act of sliding the lower front frame member in the second direction involves sliding the lower front frame member in a generally vertical direction.

[0080] Preferably, the action of sliding the corresponding height adjustment member in the first direction is performed before the action of sliding the lower front frame member in the second direction. This sequence is particularly advantageous when the action of sliding the corresponding height adjustment member in the first direction involves sliding the corresponding height adjustment member in a substantially horizontal direction, and the action of sliding the lower front frame member in the second direction involves sliding the lower front frame member in a substantially vertical direction.

[0081] The method may further include: when the corresponding height adjustment member and the lower front frame member are attached to the corresponding lower front corner portion of the corresponding side wall, the corresponding height adjustment member abuts the lower front frame member, thereby preventing the corresponding height adjustment member from moving in a direction opposite to the first direction and being released by the lower front frame member.

[0098] In the following, the installation of the furniture module 1 will be briefly described.

[0099] like Figure 1 As shown, the installation of the furniture module 1 begins by connecting the side walls 10a-10b to the flexible rear wall panel arrangement 20. Figure 2b to Figure 2c As shown in FIG. 1 , the first height adjustment member 30a and the second height adjustment member 30b can be mounted to the front lower corner 10aFLCP, 10bFLCP of each of the side walls 10a to 10b. Figure 3a to Figure 3b As shown, after the first height adjustment member 30 a and the second height adjustment member 30 b are installed, the lower front frame member 40 may be installed, whereby the side walls 10 a - 10 b may be connected via the lower front frame member 40 . Figure 6aThe third height adjustment member 30c and the fourth height adjustment member 30d are shown mounted to the rear lower corner portions 10aRLCP, 10bRLCP of the side wall. Figure 7a to Figure 7b Finally, the installation of the shelf can be achieved by positioning the shelf between the side walls 10a-10b, such as Figures 8a to 9d As seen in.

[0100] The first height adjustment member 30a is installed by inserting the first pin 30a1 and the second pin 30a2 of the first height adjustment member 30a into the first recess 11a and the second recess 12a of the front lower corner portion 10aFLCP of the first side wall 10a, respectively. Similarly, the second height adjustment member 30b is installed by inserting the first pin 30b1 and the second pin 30b2 of the second height adjustment member 30b into the first recess 11b and the first recess 12b of the front lower corner portion 10bFLCP of the second side wall 10b, respectively. The height adjustment members 30a-30b are fixed to the corresponding side walls 10a-10b by their respective pins 30a1, 30a2, 30b1, 30b2 being firmly fitted inside their corresponding recesses 11a, 12a, 11b, 12b. In the intended use of the furniture module 1, the height adjustment members 30a-30b abut against the side walls 10a, 10b and the surface on which the furniture module 1 is supported, respectively. Additionally, in the case where the lower front member 40 is installed, the height adjustment members 30a-30b abut against the lower front member 40, so that the height adjustment members 30a-30b are substantially immobile. By mounting the first height adjustment member 30a and the second height adjustment member 30b to the front lower corner 10aFLCP, 10bFLCP of each of the side walls 10a-10b, the furniture module 1 can be adapted to surfaces with different topological characteristics by adjusting the first height adjustment member 30a and the second height adjustment member 30b.

[0101] The installation of the lower front frame member 40 is firstly achieved by inserting the first pin 41a and the second pin 42a on the first side 40a of the lower front frame member 40 into the first recess 11a and the second recess 11b, respectively. The installation is further achieved by inserting the first pin 41b and the second pin 42b on the second side 40b of the lower front frame member 40 into the first recess 12a and the second recess 12b, respectively. In the intended use of the furniture module, the lower front frame member 40 abuts against a surface for supporting the furniture module. The pins 41a, 42a, 41b, 42b of the lower front frame member 40 are fixed in their corresponding recesses 11a-11b, 12a-12b so that the front lower corner portions 10aFLCP, 10bFLCP of the side walls 10a-10b are fixed at a certain distance from each other, so that the front lower corner portions 10aFLCP, 10bFLCP of the side walls 10a-10b are substantially immovable.

[0102] The third height adjustment member 30c is installed by inserting the first pin 30c1 and the second pin 30c2 of the third height adjustment member 30c into the third recess 11c and the fourth recess 12c of the rear lower corner portion 10aRLCP of the first side wall 10a, respectively. Similarly, the fourth height adjustment member 30d is installed by inserting the first pin 30d1 and the second pin 30d2 of the fourth height adjustment member 30d into the third recess 11d and the fourth recess 12d of the front lower corner portion 10bFLCP of the second side wall 10b, respectively. Installation of the third height adjustment member 30c and the fourth height adjustment member 30d Figures 6a to 6c The height adjustment members 30c-30d are fixed to the respective side walls 10a-10b by their respective pins 30c1, 30c2, 30d1, 30d2 being securely fitted inside their respective recesses 11c, 12c, 11d, 12d. In the intended use of the furniture module 1, the height adjustment members 30c-30d abut against the side walls 10a, 10b and the surface on which the furniture module 1 is supported, respectively. Figures 6a to 6c, the first blocking member 31a can be configured to be inserted into the third recess 11c and the fourth recess 12c. When the third recess 11c and the fourth recess 12c receive the first blocking member 31a, the height adjustment member 30c abuts the first blocking member 31a, so that the height adjustment member 30c is substantially immovable. Similarly, the second blocking member 31b is configured to be inserted into the third recess 11d and the fourth recess 12d. When the third recess 11d and the fourth recess 12d receive the first blocking member 31b, the height adjustment member 30d abuts the second blocking member 31b, so that the height adjustment member 30d is substantially immovable. By mounting the third height adjustment member 30c and the fourth height adjustment member 30d to the rear lower corner 10aRLCP, 10bRLCP of each of the side walls 10a-10b, the furniture module 1 has the further potential to adapt to surfaces with different topological characteristics by adjusting the third adjustment member 30c and the fourth height adjustment member 30d.

[0103] The installation of the lower rear frame member 43 is first achieved by connecting the first slit 43a1 of the first side portion 43a of the lower rear frame member 43 to the first track 32a of the third height adjustment member 30c. The installation of the lower rear frame member 43 is further achieved by connecting the second slit 43b1 of the second side portion 43b of the lower rear frame member 43 to the second track 32b of the fourth height adjustment member 30d. Figure 7a to Figure 7b By connecting the first slit 43a1 and the second slit 43b1 of the lower rear member 43 to the tracks 32a, 32b associated with the first slit 43a1 and the second slit 43b1 of the height adjustment members 30c-30d, the rear lower corners 10aRLCP, 10bRLCP of each of the side walls 10a-10b are fixed at a fixed distance from each other, so that the rear lower corner portions 10aFLCP, 10bFLCP of the side walls 10a-10b are substantially immovable relative to each other.

[0104] The installation of the shelf 50 is achieved by inserting the front pins 53a-53b on each side 50a-50b of the shelf 50 and the central pins 54a-54b on each side 50a-50c of the shelf into the front recesses 13a-13b and the central recesses 14a-14b associated with the front pins and the central pins of the corresponding top portions of the side walls 10a-10b. Alternatively, the front pins 53a-53b and the central pins 54a-54b are each configured to be inserted into the associated front recesses 13a-13b and the central recesses 14a-14b of the corresponding portions of the side walls 10a-10b. The associated front recesses 13a-13b and the central recesses 14a-14b can be arranged on the top portion, the central portion or the lower portion of the side walls 10a-10b. Therefore, the front recesses 13a-13b and the central recesses 14a-14b can be arranged at any position along the vertical extension of the sidewalls 10a-10b. Additionally, at least one shelf locking member 60a-60b is configured to be attached to the sidewalls 10a-10b. The shelf locking members 60a-60b include pins 53a-53b, which can be inserted into the recesses 55a-55b formed in the downward facing main surface 501 of the shelf 50. This arrangement fixes the shelf 50 in the expected installation position. In addition, in the expected installation position of the shelf 50, each side 50a-50b of the shelf 50 abuts the corresponding top portion of the sidewalls 10a-10b, thereby keeping the distance between the corresponding top portions of the sidewalls 10a-10b fixed.

[0105] like Figure 1 As can be seen in the figure, the two opposing side walls 10a-10b are connected to each other by the flexible rear wall panel device 20. Preferably, the longitudinally extending edge of each of the two opposing side walls 10a-10b is connected to the corresponding longitudinally extending edge of the flexible rear wall panel device 20. Each of the two opposing side walls 10a-10b can be connected to the flexible rear wall panel device 20 by means of, for example, screws, nails, adhesives, bolts, snap-fit ​​mechanisms or any other equivalent means commonly used in the art.

[0106] Go to Figure 2a The first height adjustment member 30a and the second height adjustment member 30b are configured to be attached to the corresponding opposite side walls 10b, 10a at the front lower corner portions 10aFLCP, 10bFLCP of the corresponding side walls 10a-10b. The front lower corner portions 10aFLCP, 10bFLCP are located on the main surfaces 10a1, 10b1 of the corresponding side walls 10a-10b facing inwardly toward the opposite side walls 10b, 10a. Figure 2bAs seen in FIG. 1 , the first height adjustment member 30a includes a first pin 30a1 and a second pin 30a2. Similarly, the second height adjustment member 30b includes a first pin 30b1 and a second pin 30b2.

[0107] like Figure 2b As shown, each of the opposing side walls 10a-10b includes a first recess 11a-11b and a second recess 12a-12b formed on an inwardly facing main surface 10a1, 10b1 facing the opposing side walls 10b, 10a. The first recess 11a-11b and the second recess 12a-12b are positioned at the front lower corner portions 10aFLCP, 10bFLCP of the corresponding side walls 10a-10b in the opposing side walls 10b, 10a.

[0108] The following describes the various parts of each of the recesses 11a-11b, 12a-12b. Figure 5a to Figure 5b 1. The portions of each of the recesses 11a-11b, 12a-12b can be best seen in FIG. Each of the recesses 11a-11b, 12a-12b at the front lower corner portions 10aFLCP, 10bFLCP includes an insertion portion 11a3, 11b3, 12a3, 12b3. Each of the recesses 11a-11b, 12a-12b includes a first locking portion 11a1, 11b1, 12a1, 12a1 extending from the insertion portion 11a3, 11b3, 12a3, 12a3 in the first direction L1. Each of the recesses 11a-11b, 12a-12b includes a second locking portion 11a2, 11b2, 12a2, 12b2 extending from the insertion portion 11a3, 11b3, 12a3, 12b3 in the second direction L2. The second direction L2 is different from the first direction L1. The first direction L1 may indicate a substantially horizontal direction. The second direction L2 may indicate a substantially vertical direction. The directions of L1 and L2 are Figure 2c Best seen in.

[0109] In a preferred embodiment, each first recess 11a~11b on each side wall panel 10a~10b is positioned at a first height H11a~H11b, and each second recess 12a~12b on each side wall panel 10a~10b is positioned at a second height H12a~H12b, wherein the first height H11a~H11b is preferably greater than the second height (H12a~H12b).

[0110] Preferably, the recesses 11a-11b, 12a-12b are positioned so that the projection of the corresponding first recesses 11a-11b on the horizontal plane and the projection of the corresponding second recesses 12a-12b on the horizontal plane at least partially overlap. More preferably, the recesses 11a-11b, 12a-12b are positioned so that the geometric line extending from the center point 11a3CP, 11b3CP of the corresponding insertion part 11a3, 11b3 of the corresponding first recesses 11a-11b to the center point 12a3CP, 12b3CP of the insertion part 12a3, 12b3 of the corresponding second recesses 12a-12b extends substantially vertically downward. By having the recesses 11a-11b, 12a-12b at different heights H11a-H11b, H12a-H12b, the force generated by gravity can be used to maintain the height adjustment member 30a-30b and / or the lower front frame member 40 in the desired position. This effect is further enhanced in case there is a horizontal overlap and even further enhanced in case a recess 11a-11b, 12a-12b is located more or less above another recess.

[0111] like Figure 2b to Figure 2c As illustrated in FIG. 1 , the first height adjustment member 30a is configured to be attached to the side wall 10a at the front lower corner portion 10aFLCP of the side wall 10a by inserting the first pin 30a1 and the second pin 30a2 into the first recess 11a and the second recess 12a of the front lower corner portion 10aFLCP of the first side wall 10a. More specifically, the first pin 30a1 and the second pin 30a2 are inserted into the insertion points 11a3, 12a3 of the corresponding recesses 11a, 12a. Once the pins 30a1, 30a2 are positioned in their associated insertion points 11a3, 12a3, the pins 30a1, 30a2 are transferred to the first locking portions 11a1, 12a1 of the corresponding recesses 11a, 12a by sliding movement along the direction L1.

[0112] Similarly, the second height adjustment member 30b is configured to be attached to the side wall 10b at the front lower corner portion 10bFLCP of the side wall 10a by inserting the first pin 30b1 and the second pin 30b2 into the first recess 11b and the second recess 12b of the front lower corner portion 10bFLCP of the opposite side wall 10b. More specifically, the first pin 30b1 and the second pin 30b2 are inserted into the insertion points 11b3, 12b3 of the corresponding recesses 11b, 12b. Once the pins 30b1, 30b2 are positioned in their associated insertion points 11b3, 12b3, the pins 30b1, 30b2 are transferred to the first locking portions 11b1 and 12b1 of the corresponding recesses 11b, 12b by sliding movement along the direction L1.

[0113] It can be noted that there may be a waist portion of slightly narrower width between the insertion portion 11a3, 11b3, 12a3, 12b3 of the corresponding recesses 11a-11b, 12a-12b and the first locking portion 11a1, 11b1, 12a1, 12a1. This may be configured to provide tactile and / or auditory feedback to the installer that the height adjustment member 30a-30b has reached the desired position. The waist portion may also be designed to provide a holding force to keep the height adjustment member 30a-30b in the desired position so that the height adjustment member 30a-30b does not interfere with the insertion of the pins 41a-41b, 42a-42b of the lower frame member 40 into the corresponding recesses 11a-11b, 12a-12b.

[0114] Figure 3a The lower front frame member 40 is illustrated, which is configured to be attached to two opposing side walls 10b, 10a at the respective front lower corner portions 10aFLCP, 10bFLCP of the respective side walls 10a-10b on the inwardly facing main surfaces 10a1, 10b1 of the respective side walls 10a, 10b facing the opposing side walls 10b, 10a. The lower front frame member 40 connects the two opposing side walls 10a-10b to each other at the front lower portion of the furniture module 1. More specifically, the lower front frame member 40 includes a first pin 41a and a second pin 42a located on the first side portion 40a. It should be understood that the first side portion 40a refers to the laterally extending side portion of the lower front frame member 40.

[0115] Similarly, the lower front frame member 40 includes a first pin 41b and a second pin 42b on the second side 40b. It should be understood that the second side 40b refers to the laterally extending side of the lower front frame member 40. The first side 40a and the second side 40b are opposite sides of the lower front frame member 40.

[0116] The first pin 41a and the second pin 42a on the first side portion 40a of the lower front frame member 40 are inserted into the insertion points 11a3, 12a3 of the corresponding recesses 11a, 12a. Once the pins 41a, 42a are positioned in their associated insertion points 11a3, 12a3, the pins 41a, 42a are transferred to the second locking portions 11a2, 12a2 of the corresponding recesses 11a, 12a by a sliding movement along the direction L2, as shown in FIG. Figure 3b as shown in .

[0117] The first pin 41b and the second pin 42b on the second side portion 40b of the lower front frame member 40 are inserted into the insertion points 11b3, 12b3 of the corresponding recesses 11b, 12b. Once the pins 41b, 42b are positioned in their associated insertion points 11b3, 12b3, the pins 41b, 42a are transferred to the second locking portions 11b2, 12b2 of the corresponding recesses 11b, 12b by sliding movement along the direction L2, as shown in FIG. Figure 3b as shown in .

[0118] Continue to refer to Figure 3b Once the pins 41a-41b, 42a-42b of the lower front frame member 40 are transferred to the second locking portions 11a2, 11b2, 12a2, 12b2 of the corresponding recesses 11a-11b, 12a-12b by sliding movement along the direction L2, the lower front frame member 40 is locked in place and abuts the installed height adjustment members 30a-30b. In this case, this may refer to a projection distance L1d between the first locking portions 11a1, 11b1, 12a1, 12a1 and the second locking portions 11a2, 11b2, 12a2, 12a2 measured along the first direction L1 such that when installed, the corresponding height adjustment members 30a-30b abut the lower front frame member 40, thereby preventing the corresponding height adjustment members 30a-30b from moving in the direction opposite to the first direction L1 and being released by the lower front frame member 40. Therefore, in this sense, abutment means that the height adjustment members 30 a - 30 b and the lower front frame member 40 respectively apply forces opposite to each other in the first direction L1 .

[0119] In this case, it can be clarified that, in a preferred embodiment, the pins 30a1, 30a2, 30b1, 30b2 of the respective height adjustment members 30a-30b are configured to be inserted into the insertion portions 11a3, 11b3, 12a3, 12b3 of the respective recesses 11a-11b, 12a-12b and the pins 41a, 42a, 41b, 42b of the lower front frame member 40 are configured to be inserted into the insertion portions 11a3, 11b3, 12a3, 12b3 of the respective recesses 11a-11b, 12a-12b and The first locking parts 11a1, 11b1, 12a1, 12a1 are inserted into the insertion parts 11a3, 11b3, 12a3, 12b3 of the corresponding recesses 11a~11b, 12a~12b before being transferred to the second locking parts 11a2, 11b2, 12a2, 12a2 of the corresponding recesses 11a~11b, 12a~12b.

[0120] like Figure 4a, the first pins 41a-41b and the second pins 42a-42b of the lower front frame member 40 are illustrated in more detail. The first pins 41a, 41b are positioned at the top portions of the respective opposite sides 40b-40a of the lower front frame member 40. The second pins 42a, 42b are positioned at the lower portions of the respective opposite sides 40b-40a of the lower front frame member 40. Each of the pins 41a-41b, 42a-42b is formed so that when installed, the pins fit securely into their associated second locking portions 11a2, 11b2, 12a2, 12b2. The pins 41a-41b, 42a-42b on each side 40a-40b of the lower front frame member 40 may extend outwardly from the major surface of each of the side 40a-40b to which the pins are attached. Each set of pins 41a-41b, 42a-42b on each side portion 40a-40b of the lower front frame member 40 may preferably extend in the same direction.

[0121] The pins 41a-41b, 42a-42b may be attached to the respective side portions 40a-40b by means of, for example, an adhesive, screwing the pins 41a-41b, 42a-42b into the lower front frame member 40, or being integrally formed with the lower front frame member 40.

[0122] Figure 4a The pins 41a-41b, 42a-42b of the lower front frame member 40 are illustrated as having a circular cross-section, an extension extending through each of the pins 41a-41b, 42a-42b along a longitudinal centerline, and having a radially extending groove. Figure 4a The pins 41a-41b, 42a-42b in the embodiment have two radially extending grooves that are approximately equidistant, but are not limited to having only two radially extending grooves that are approximately equidistant. For example, the pins 41a-41b, 42a-42b may have, for example, three or four radially extending grooves, which may be at different distances relative to each other. Therefore, those skilled in the art will appreciate that there is no limit to the number of grooves that the pins 41a-41b, 42a-42b may have. The pins 41a-41b, 42a-42b are not limited to circular cross-sections, as long as the recesses 11a-11b, 12a-12b are formed to accommodate different cross-sections of the pins 41a-41b, 42a-42b. For example, the cross-sections of the pins 41a-41b, 42a-42b may be, for example, wedge-shaped, hexagonal, square, rectangular, triangular, octagonal, or any other cross-section. The pins 41a-41b, 42a-42b are preferably identical.

[0123] The first pin 30a1 of the first height adjustment member 30a may be attached to the top portion of the first height adjustment member 30a and may extend outward from the main surface of the first height adjustment member 30a. The second pin 30a2 may be attached to the lower portion of the first height adjustment member 30a and may extend outward from the main surface of the first height adjustment member 30a. The first pin 30a1 and the second pin 30a2 may preferably extend in the same direction.

[0124] The first pin 30b1 may be attached to the top portion of the second height adjustment member 30b and may extend outward from the main surface of the first height adjustment member 30b. The second pin 30b2 may be attached to the lower portion of the first height adjustment member 30b and may extend outward from the main surface of the first height adjustment member 30b. The first pin 30b1 and the second pin 30b2 may preferably extend in the same direction.

[0125] The pins 30a1, 30a2, 30b1, 30b2 can be attached to the corresponding height adjustment members 30a-30b by means of, for example, an adhesive, screwing the pins 30a1, 30a2, 30b1, 30b2 into the main surface of the corresponding height adjustment member 30a-30b, or being integrally formed with the main surface of the corresponding height adjustment member 30a-30b. In a preferred embodiment, the body portion of the height adjustment member 30a-30b is formed by molding of a plastic material, such as injection molding, wherein the pins 30a1, 30a2, 30b1, 30b2 are integrally formed with the body portion in the molding.

[0126] The pins 30a1, 30a2, 30b1, 30b2 of the height adjustment members 30a-30b may have a circular cross-section, an extension extending through each of the pins 30a1, 30a2, 30b1, 30b2 along a longitudinal centerline, and may have a radially extending groove. The pins 30a1, 30a2, 30b1, 30b2 may have two radially extending grooves that are approximately equidistant, but are not limited to having only two radially extending grooves that are approximately equidistant. For example, the pins 30a1, 30a2, 30b1, 30b2 may have, for example, three or four radially extending grooves, which may be at different distances relative to each other. Therefore, those skilled in the art recognize that there is no limit to the number of grooves that the pins 30a1, 30a2, 30b1, 30b2 may have. The pins 30a1, 30a2, 30b1, 30b2 are not limited to circular cross-sections, as long as the recesses 30a1, 30a2, 30b1, 30b2 are formed to accommodate different cross-sections of the pins 30a1, 30a2, 30b1, 30b2. For example, the cross-sections of the pins 30a1, 30a2, 30b1, 30b2 may be, for example, wedge-shaped, hexagonal, square, rectangular, triangular, octagonal, or any other cross-sections.

[0127] The pins 30a1 , 30a2 , 30b1 , 30b2 are preferably identical.

[0128] Figure 4b The pins 30a1, 30a2, 30b1, 30b2 are shown with the portion thereof extending along the longitudinal centerline through each of the pins 30a1, 30a2, 30b1, 30b2 omitted. This is done in view of the fact that it is beneficial to have a uniform thickness of polymer material so that uneven shrinkage does not occur during cooling of the molded part.

[0129] Figure 5a to Figure 5b Recesses 11a-11b, 12a-12b positioned at the front lower corner portions 10aFLCP, 10bFLCP of the respective side walls 10a-10b are shown. Figure 5a to Figure 5b The recesses 11a-11b, 12a-12b are shown to be identical. However, this may not always be the case. Figure 5a to Figure 5b Specifically shown are respective recesses 11a-11b, 12a-12b having circular insert portions 11a3, 11b3, 12a3, 12b3. The shapes of the insert portions 11a3, 11b3, 12a3, 12b3 are not limited to circular shapes, but may be, for example, hexagonal, square, rectangular, triangular, octagonal, or any other form that still allows the height adjustment members 30a-30b and the lower front frame member 40 to be attached to the front lower corner portions 10aFLCP, 10bFLCP of the side walls 10a-10b.

[0130] also, Figure 5a to Figure 5b The first locking portions 11a1, 11b1, 12a1, 12a1 extending from the insertion portions 11a3, 11b3, 12a3, 12a3 along the first direction L1 are shown, which include a portion that tapers gradually and ends with a rounded end portion. Therefore, once the sliding movement of the inserted height adjustment member 30a-30b from the insertion portion 11a3, 11b3, 12a3, 12b3 along the direction L1 toward the corresponding first locking portion 11a1, 11b1, 12a1, 12a1 is performed, the pins 30a1, 30a2, 30b1, 30b2 of the corresponding height adjustment member 30a-30b are gradually restricted from moving in a direction transverse to the direction L1 until the pins 30a1, 30a2, 30b1, 30b2 reach the rounded end portion of the corresponding first locking portion 11a1, 11b1, 12a1, 12a1.

[0131] Additionally, Figure 5a to Figure 5b The second locking portions 11a2, 11b2, 12a2, 12b2 extending from the insertion portions 11a3, 11b3, 12a3, 12b3 along the second direction L2 are shown, and include portions that taper gradually and end with rounded end portions. Therefore, once the inserted lower front frame member 40 performs sliding movement from the insertion portions 11a3, 11b3, 12a3, 12b3 along the direction L2 toward the corresponding second locking portions 11a2, 11b2, 12a2, 12b2, the pins 41a-41b, 42a-42b of the corresponding lower front frame member 40 are gradually restricted from moving in a direction transverse to the direction L2 until the pins 41a-41b, 42a-42b reach the rounded end portions of the corresponding second locking portions 11a2, 11b2, 12a2, 12b2.

[0132] As shown in the drawings, the corresponding insertion portion 11a3, 11b3, 12a3, 12b3 of each recess 11a-11b, 12a-12b has an insertion portion width IPW measured in a direction transverse to the depth direction DD, measured transverse to the first direction L1 and measured transverse to the second direction L2.

[0133] The corresponding first locking parts 11a1, 11b1, 12a1, 12a1 and the corresponding second locking parts 11a2, 11b2, 12a2, 12b2 each have relative recess side walls SW1, SW2, which face each other and each have an extension along the depth direction DD and along the first direction L1 and the second direction L3 respectively. Each of the opposing recess side walls SW1, SW2 is preferably provided with: at least one ridge R1, R2, wherein each ridge R1, R2 is positioned at a ridge depth RD as viewed along the depth direction DD, and each ridge R1, R2 has a longitudinal extension LR along the shelf sliding direction L3 and a height HR extending from the corresponding recess side wall SW1, SW2 toward the opposing ridge R2, R1 of the opposing recess side wall SW2, SW1; and at least one valley V1, V2 positioned at a valley depth VD, the valley depth VD being greater than the ridge depth RD. The locking portion width LPW formed by the shortest distance SDR between the opposing ridges R1, R2 is smaller than the insertion portion width IPW and smaller than the shortest distance SDV between the opposing valleys V1, V2.

[0134] Continue to refer to Figure 5a to Figure 5b , Figure 5a to Figure 5b The angle between the first locking portion 11a1, 11b1, 12a1, 12a1 and the second locking portion 11a2, 11b2, 12a2, 12b2 is shown to be approximately 90 degrees. However, the angle between the first locking portion 11a1, 11b1, 12a1, 12a1 and the second locking portion 11a2, 11b2, 12a2, 12b2 is not limited to a specific angle. It is appreciated by those skilled in the art that the recesses 11a-11b, 12a-12b can be sized to achieve the following state: the corresponding height adjustment member 30a-30b abuts the lower front frame member 40, thereby preventing the corresponding height adjustment member 30a-30b from moving in a direction opposite to the first direction L1 and being released by the lower front frame member 40.

[0135] Figure 8a Shelf locking members 60a-60b are shown, each of which has a body portion 61a-61b configured to be attached to the side walls 10a-10b and a pin 62a-62b movably connected to the corresponding body portion 61a-61b. The pins 62a-62b are movable between a shelf insertion position, in which the shelf 50 can be inserted between the side walls 10a-10b to the intended installation position of the shelf 50, and a shelf locking position, in which the pins 62a-62b are inserted into recesses 55a-55b formed in the downward-facing main surface 501 of the shelf 50 and interact with the recesses 55a-55b. The shelf locking position is Figure 12b best shown. This configuration prevents the shelf 50 from being removed from the intended installation position of the shelf 50. In the disclosed embodiment, the corresponding pins 62a-62b are arranged on arms 63a-63b that are flexibly connected to the body portions 61a-61b. The arms 63a-63b are able to move between shelf insertion positions, in which the arms 63 are folded relative to the body portions 61a-61b so that the pins 62a-62b are in their shelf insertion positions to allow the shelf 50 to be inserted between the side walls 10a-10b into the intended installation position of the shelf 50. Once the shelf 50 has been positioned in the installation position, the flexible arms 63a-63b are able to move to the shelf locking position, in which the pins 62a-62b move to their shelf locking positions and are inserted into the recesses 55a-55b. The body portions 61a-61b are also provided with protrusions 64a-64b, 65a-65b configured to hold the flexible arms 63a-63b in the shelf insertion position. In the disclosed embodiment, the arms 63a-63b are configured to be manually positioned in the shelf insertion position. However, it is also conceivable that the flexible arms 63a-63b or the pins 62a-62b are provided with cam surfaces configured to interact with the main edge, i.e. the rear edge, of the shelf 50 so that the pins 62a-62b are automatically positioned in the shelf insertion position when the shelf insertion occurs. It is also conceivable that the pins 62a-62b are already positioned in the shelf insertion position from the beginning; in this sense, the shelf locking members 60a-60b are initially delivered to the user in a state in which the pins 62a-62b are preset to be in the shelf insertion position. In the disclosed embodiment, the arms 63a-63b are configured to be manually positioned into the shelf locking position once the shelf 50 reaches the intended installation position. However, it is also conceivable that the flexible arms 63a-63b, the pins 62a-62b, or the protrusions 64a-64b, 65a-65b are provided with a cam surface that interacts with the downward facing main surface 501 of the shelf 50 so that the flexible arms 63 are automatically released from the protrusions 64a-64b, 65a-65b. For example, as soon as the main edge, i.e., the rear edge, of the shelf 50 has passed the pins 62a-62b, the release of the arms 63a-63b will occur, so that the pins 62a-62b slide along the downward facing main surface 501 of the shelf 50 until the shelf 50 reaches the intended installation position and the pins 62a-62b can be inserted into the recesses 55a-55b.

[0136] The furniture module 1 may comprise at least two shelf locking members 60a-60b. Figure 8b to Figure 8c As seen in FIG. 1 , each of the shelf locking members 60a-60b is configured to be attached to a corresponding side wall of two opposing side walls 10a-10b. Figure 8cIn the embodiment, the shelf locking members 60a-60b are attached to the corresponding side walls of the two opposite side walls 10a-10b by means of pins attached to the corresponding body parts 61a-61b inserted into the transversely extending openings of the side walls 10a-10b. It is appreciated by those skilled in the art that the shelf locking members 60a-60b can be attached to the corresponding side walls of the two opposite side walls 10a-10b by equally effective methods commonly used in the art.

[0137] Figures 9a to 9d The various stages of installing the shelf 50 to the furniture module 1 are illustrated. The shelf 50 is configured to be positioned between the side walls 10a-10b. The shelf 50 is not limited to being positioned in a corresponding specific portion between the side walls 10a-10b, but is preferably positioned between the corresponding top portions of the side walls 10a-10b. The shelf is provided with front pins 53a-53b on each side 50a-50b of the shelf 50. The shelf is also provided with central pins 54a-54b on each side 50a-50b of the shelf 50. Viewed from above, the shelf 50 is preferably in a generally rectangular shape.

[0138] like Figure 9b As best seen in FIG. 1 , each of the opposing side walls 10a-10b includes a front recess 13a-13b and a central recess 14a-14b formed on an inwardly facing major surface 10a1, 10b1 facing the opposing side walls 10b, 10a. Each of the front recesses 12a-12b is positioned at a front top corner portion of the corresponding side wall 10a-10b. Each of the central recesses 14a-14b is positioned in a central top portion of the corresponding side wall 10a-10b.

[0139] However, the front recesses 13a-13b and the central recesses 14a-14b can be arranged at any position along the vertical extension of the corresponding side walls 10a-10b. Therefore, each of the front recesses 13a-13b can be positioned as a middle front recess 13a-13b or a lower front recess 13a-13b along the longitudinally extending edge. Each of the central recesses 14a-14b can be positioned in the central middle part or the central lower part of the corresponding side walls 10a-10b. In one embodiment, the front pins 53a-53b and the central pins 54a-54b are each configured to be inserted into the front recesses 13a-13b and the central recesses 14a-14b associated therewith arranged in the longitudinal vertical extension of the side walls 10a-10b.

[0140] The front top corner recesses 13a-13b and the central top recesses 14a-14b each include an insertion portion 13a3, 13b3, 14a3, 14b3 and a locking portion 13a1, 13b1, 14a1, 14b1 extending from the insertion portion 11a3, 11b3, 12a3, 12a3 along a third direction L3. In a preferred embodiment, the third direction L3 is substantially horizontal. As described above, in a preferred embodiment, the first direction L1 is substantially horizontal. Therefore, in a preferred embodiment, the first direction L1 and the third direction L3 are substantially parallel to each other.

[0141] Now according to Figures 9a to 9d The installation of the shelf 50 is described in detail.

[0142] Figure 9a The shelf 50 is shown inserted between the top portions of the side walls 10a-10b. The flexible rear wall panel assembly 20 is configured to allow the opposing side walls 10a-10b to be in a shelf mounted position. Figure 9a , the user installing the furniture module 1 attaches the shelf locking members 60a-60b in the rear top corner portions of the side walls 10a-10b. Then, the user inserts the shelf 50 obliquely relative to the directions L1, L3. In this position, the horizontal distance between the front portions of the side walls 10a-10b is greater than the horizontal distance between the rear portions of the side walls 10a-10b.

[0143] Figure 9b The obliquely positioned shelf 50 is shown moved to a generally horizontal position.

[0144] Fig.9c The effect of the front portions of the side walls 10a-10b being spaced apart horizontally at a greater distance from each other than the rear portions of the side walls 10a-10b is demonstrated, which allows the shelf 50 to be fitted between the top portions of the side walls 10a-10b, thereby allowing the shelf 50 to be inserted by moving along the first direction L1 until the pins 53a-53b, 54a-54b reach the corresponding associated recesses 13a-13b, 14a-14b.

[0145] Figure 9d As shown in the figure, after the corresponding pins 53a~53b, 54a~54b are inserted into the insertion parts 13a3, 13b3, 14a3, 14b3 of the corresponding recesses 13a~13b, 14a~14b, the shelf 50 can be further moved along the third direction L3 so that the corresponding pins 53a~53b, 54a~54b are transferred to the locking parts 13a1, 13b1, 14a1, 14a1 of the corresponding recesses 13a~13b, 14a~14b.

[0146] Go to Figure 10a to Figure 10b, showing that the front pins 53a-53b located on each side 50a-50b of the shelf 50 can extend a first distance 53ad1, 53bd1 from the respective side 50a-50b of the shelf 50 to the respective free ends 53ae, 53be of the respective pins 53a, 53b. In addition, the central pins 54a-54b can extend a second distance 54ad2, 54bd2 from the respective side 50a-50b of the shelf 50 to the respective free ends 54ae, 54be of the respective pins 54a, 54b on each side 50a-50b of the shelf 50. The first distance 53ad1, 53bd1 is greater than the second distance 54ad2, 54bd2.

[0147] When the shelf 50 is inserted between the top portions of the side walls 10a-10b, the opposite side walls 10a-10b are in a shelf installation position, in which the distance between the front top corner portions of the corresponding opposite side walls 10a-10b is greater than the distance between the central top portions of the corresponding opposite side walls 10a-10b, and the distance between the central tops of the corresponding opposite side walls 10a-10b is greater than the distance between the rear top corner portions of the corresponding side walls 10a-10b. Since the distances 53ad1, 53bd1 are greater than the second distances 54ad2, 54bd2, the pins 53a-53b, 54a-54b of the shelf 50 can synchronously reach the corresponding associated recesses 13a-13b, 14a-14b, thereby allowing the shelf 50 to be properly fitted between the top portions between the opposite side walls 10a-10b. For example, Figure 10b to Figure 10c It is best illustrated in the figure that the distance 53ad1, 53bd1 is greater than the second distance 54ad2, 54bd2, the length of the front pins 53a~53b of the shelf 50 is approximately twice the length of the central pins 54a~54b, and the length of each pin in the corresponding pins 53a~53b, 54a~54b is limited to the length of the extension portion extending through each pin in the corresponding pins 53a~53b along the longitudinal center line.

[0148] exist Fig.11 , the recessed portions 13a-13b, 14a-14b of each of the corresponding opposing side walls 10a-10b are shown in more detail.

[0149] Each of the opposing side walls 10a-10b includes front recesses 13a-13b and central recesses 14a-14b formed on the inwardly facing main surfaces 10a1, 10b1 facing the opposing side walls 10b, 10a. The front recesses 13a-13b and the central recesses 14a-14b are located in the front top corner portion and the central top portion of the corresponding side walls 10a-10b, respectively.

[0150] As described above, the front top corner recesses 13a~13b and the central top recesses 14a~14b each include an insertion portion 13a3, 13b3, 14a3, 14b3 and a locking portion 13a1, 13b1, 14a1, 14b1 extending from the insertion portion 13a3, 13b3, 14a3, 14a3 along the third direction L3.

[0151] In this case, it can be noted that in Fig.11 , the top shelf 50 is moved a distance away from the side wall panel 10a only for clarity reasons.

[0152] The process of achieving installation of shelf 50 will now be described in more detail.

[0153] like Figure 9d As seen in the figure, after the corresponding pins 53a~53b, 54a~54b are inserted into the insertion parts 13a3, 13b3, 14a3, 14b3 of the corresponding recesses 13a~13b, 14a~14b, the shelf 50 can be further moved along the third direction L3 so that the corresponding pins 53a~53b, 54a~54b are transferred to the locking parts 13a1, 13b1, 14a1, 14a1 of the corresponding recesses 13a~13b, 14a~14b. From this stage, the shelf locking members 60a-60b are attached to the rear corner portions of the side walls 10a-10b, and the pins 62a-62b of the shelf locking members 60a move between the shelf insertion position, in which the shelf 50 can be inserted between the side walls 10a-10b to the intended installation position of the shelf 50, and the shelf locking position, in which the pins 62a-62b interact with the recesses 55a-55b formed in the downward facing main surface 501 of the shelf 50. By doing so, the shelf 50 is prevented from sliding in the direction opposite to the direction L3. In other words, the shelf 50 is prevented from being removed from the intended installation position of the shelf 50.

[0154] Although it is preferred that the furniture module is designed according to the disclosure in the preferred embodiments and detailed disclosure of the drawings, it should be noted that a particular preferred embodiment of a particular component is not necessarily combined with a particular embodiment of another component. Thus, advantages associated with a particular embodiment of a particular component including one or more features may be achieved even if the other component is designed according to the more general disclosure under the summary of the invention rather than being limited to the specific embodiments disclosed in the detailed description.

[0155] It is conceivable that there are numerous modifications of the embodiments described herein which still fall within the scope of the invention as defined by the appended claims.
