Abstract
Description
[0001] MOVEMENT SYSTEM FOR CONTAINERS OF FURNITURE ITEMS The present invention concerns a system for moving containers, such as baskets or drawers or the like, with respect to an opening of a compartment of a furniture item, and concerns a furniture item equipped with the system.
[0002] For example, in the kitchen furniture field, the use of articulated mechanisms that allow baskets to be moved from inside the furniture item to the outside is well known. A specific example is described in W02020079643, where a pair of baskets, aligned horizontally within the furniture item, is movable along a horizontal plane so that the first basket can be extracted from the compartment, simultaneously causing the second basket to move, following the first. To this end, the two baskets are connected to each other by an articulated system of arms and levers, which, however, is complicated, involves many parts, and is expensive.
[0003] The main object of the invention is to eliminate or mitigate the above-mentioned drawbacks by creating a different system of the above-mentioned type.
[0004] A movement system is then proposed for members of a furniture item installed inside a compartment of the furniture item, the compartment comprising
[0005] an opening,
[0006] a rear wall opposite the opening, and
[0007] a first zone and a second zone adjacent to each other, wherein
[0008] the first zone is located between the opening and the back wall and the second zone is located to the side of the first zone along the rear wall; the system comprising:
[0009] a first container and a second container mounted inside the compartment, wherein the first container is mounted slidable inside the compartment along a first horizontal axis so that it can be extracted from the first zone through said opening, and
[0010] the second container is mounted slidable inside the compartment to translate along a second horizontal axis, orthogonal to the first axis, from the second zone to the first zone to align itself along the first axis queuing up behind the first container when the first container is in extracted position with respect to the compartment, wherein
[0011] the first container and the second container are coupled so as to interact with each other by converting a (e.g. manual) push on the first container, directed along the first axis towards the rear wall, into a force, e.g. a push, on the second container directed along the second axis to move the second container, which is queued up behind the first container, from the first to the second zone.Advantageously, the aforementioned kinematics can be easily implemented in practice, with inexpensive and relatively simple means.
[0012] Advantageously, the first container is adapted to push directly against the second container to move it from the first to the second zone.
[0013] In one embodiment, the first container is adapted to directly pull the second container to move it from the second to the first zone.
[0014] In one embodiment the first and second containers comprise respective portions that are
[0015] configured to contact each other when, preferably only when, the second container is queued up behind the first container, and
[0016] configured so that said push on the first container determines
[0017] a relative, preferably linear, sliding between said portions and
[0018] consequently a translation of the second container, inside the compartment along the second axis, which moves it towards the second zone to make it abandon its position in the first zone queuing the first container.
[0019] In one embodiment at least one of said portions comprises or consists of a plane inclined at an acute angle to the first axis, or which is oriented and extends parallel to a bisector of the angle formed by the first and second axes.
[0020] In particular, both said portions comprise or consist of an inclined plane that is oriented and extends parallel to the same bisector of the angle formed by the first and second axes. Said inclined planes are adapted to slide relatively on each other in order to push the second container along the second axis toward and / or away from the second zone following a push on the first container directed along the first axis toward and / or away from the rear wall, respectively.
[0021] In one embodiment, one of said portions comprises or consists of an inclined plane that is oriented and extends parallel to a bisector of the angle formed by the first and second axes, and the other of said portions comprises or consists of a member which is mounted integral with the relative container and slidable along said inclined plane. Said member and said inclined plane are adapted to slide relatively to push the second container along the second axis toward and / or away from the second zone following a push on the first container directed along the first axis toward and / or away from the rear wall, respectively.
[0022] A push in the opposite direction on the first container allows the movements of the two containers to be reversed.
[0023] Said portions can be easily made without complicated mechanisms, In particular bydirectly shaping the first and second vertical planes (see below) or by mounting on them additional components functioning as said portions.
[0024] In one embodiment, also valid for implementing said portions,
[0025] the first container comprises a first vertical plane which is
[0026] - inclined with respect to the first axis and
[0027] - facing said rear wall, and
[0028] the second container comprises a second vertical plane which is
[0029] - inclined in a complementary manner to the first inclined plane and
[0030] - facing the first inclined plane;
[0031] the first vertical plane and the second vertical plane being adapted to interact with each other, when the second container is queuing up behind the first container and a thrust is exerted on the first container along the first axis towards the rear wall, so as to cause a relative sliding of said vertical planes and consequently a translation of the second container inside the compartment along the second axis towards the second zone.
[0032] In one embodiment the first vertical plane and the second vertical plane are in direct contact with each other.
[0033] Advantageously, the first vertical plane, through its inclination, acts on the second vertical plane to push it into the compartment laterally with respect to the first axis, without additional mechanisms. The result is a structure that is simple to build, inexpensive but effective, and with very little risk of breakage or jamming.
[0034] In one embodiment, the first and second containers comprise vertical walls that delimit a loading space in the shape of a right-angled trapezoid, or said walls are arranged like the sides of a right-angled trapezoid and give the first and second containers a right-angled trapezoid plan.
[0035] In one embodiment, the inclination of the oblique side of each trapezoid with respect to one of the bases is substantially equal. Preferably, the height of each trapezoid is substantially equal.
[0036] In one embodiment, said portions, or the first vertical plane and the second vertical plane are made at, or by inclination of, the oblique sides of said trapeziums.
[0037] In one embodiment, said portions, or the first vertical plane and the second plane vertical, coincide with the oblique sides of said trapeziums and with the vertical walls that constitute the oblique sides of said trapeziums.
[0038] In one embodiment the vertical walls constituting the oblique sides of said trapeziums are mounted facing each other and able to slide relatively.In one embodiment, to smooth the relative sliding between the first vertical plane and the second vertical plane, the system comprises rolling members mounted between the first vertical plane and the second vertical plane, or between said portions.
[0039] In one embodiment, which facilitates sliding, the second container comprises first rolling members mounted to slide on the rear wall of the furniture item.
[0040] In one embodiment, which facilitates sliding, the second container comprises second rolling members mounted so as to slide on the first vertical plane. In particular, the second rolling members are mounted on the second vertical plane.
[0041] To limit noise, preferably the first and / or second rolling members are made of rubber or polyurethane (absorbs noise).
[0042] Preferably the first and / or second rolling members have a vertical rotation axis.
[0043] To automate the movement of the containers, the system preferably comprises means for automatically (without manual intervention or action) pushing the second container along the second axis and bring it queued up behind the first container.
[0044] To automate the sliding of the containers, the system preferably comprises means for automatically pushing (without manual intervention or action) the second container against the first container along the second axis to bring it queued up behind the first container.
[0045] In one embodiment, the means for moving comprise an inclined plane on which the second container rests and is free to translate, so that the second container translates along the second axis from the second zone toward the rear of the first container and toward the first zone by gravity.
[0046] In one embodiment, the means for moving comprises an actuator member connected to the second container mounted to exert a force on the second container and cause it to translate along the second axis from the second zone towards the first zone to bring it queued up behind the first container.
[0047] In one embodiment, the actuator member is or comprises an elastic member, e.g. a spring, mounted to push or pull the second container along the second axis.
[0048] In one embodiment, said portions or inclined plane may belong to a guide integral with the first or second container.
[0049] In particular, the system may comprise a horizontal L or V-shaped guide mounted on one of the first or second container,
[0050] the other container comprising a slider member, preferably fixed, e.g. a pin and / or a wheel, which is slidably coupled with the guide,
[0051] the guide and the slider member being dynamically coupled so thatthe movement to put the first container back into the compartment determines the sliding of the fixed member inside the guide and
[0052] such sliding, together with the interaction of the slider member with the walls of the guide, induces said force on the second container.
[0053] In one embodiment the guide may also provide said means for moving, so the guide and the slider member are dynamically coupled so that
[0054] the movement to extract the first container from the compartment determines the (reverse) sliding of the slider member inside the guide and
[0055] such sliding, together with the interaction of the slider member with the walls of the guide, induces a force on the second container which drags it from the second to the first zone.
[0056] By L or V-shaped guide it is generally understood a guide whose guided path recalls and / or comprises an L or V where the L and the V form a preferably obtuse angle at the center.
[0057] In one embodiment, the guide comprises two guide sections connected to each other at a common vertex.
[0058] In a more preferred embodiment, said two guide sections form an obtuse angle at the common vertex.
[0059] In a more preferred embodiment said two guide sections comprise:
[0060] a first guide section which is mounted on the respective container parallel to the first axis, and
[0061] a second guide section which is mounted on the respective container obliquely to the first axis (arranged parallel to a bisector of the angle formed by the first and second axes).
[0062] In one embodiment, the first and second guide sections are mounted along respective sides of the container.
[0063] In one embodiment, the second zone is equipped with a fixed support plane on which the second container can slide back and forth along the second axis to move from the second zone to the first zone and vice versa. In particular, the fixed support plane coincides with said inclined plane.
[0064] Preferably, the second container comprises third rolling members with a rotation axis parallel to the first axis, in particular mounted to roll on the fixed support plane.
[0065] Preferably, said rolling members are wheels, more preferably with a minimum diameter of 40 mm, to absorb rolling noise.
[0066] Another advantage of the first and / or second rolling members is that they carry thesecond container from the second zone to the first zone climbing over the empty space that may form at said opening before reaching the first vertical plane.
[0067] In one embodiment, the system comprises a telescopic structure or means for jointly and together moving the first and second containers away from the compartment when the second container is in the first zone and queued up behind the first container.
[0068] In one embodiment, the system comprises first guide means or a first guide for translating the first container relative to the second container (and the first platform) outwards from the compartment along the first axis when the second container is present in the second zone.
[0069] In one embodiment, the system comprises second guide means or a second guide for integrally translating the first container and the second container out of the compartment along the first axis when the second container is in the first zone and queued up behind the first container.
[0070] In one embodiment, the first guide means or the first guide are mounted on the second guide means or the second guide so that the first guide means or the first guide can translate along the first axis relative to the second guide means or the second guide. In one embodiment, the first guide means and the second guide means form a telescopically extendable structure.
[0071] In one embodiment, the system comprises a first platform located in the first zone and guided translatably along the first axis to translate from the first zone toward the outside of the compartment, the first platform being mounted to receive on itself from the second zone the second container and make it translate along the first axis. In particular, the first platform is positioned flush with said fixed support plane.
[0072] In one embodiment, the first platform comprises a support member, or a second translatable platform, that is connected to the first container and mounted to translate the first container relative to the first platform outwards from the compartment along the first axis.
[0073] In one embodiment, said support member or second translatable platform is comprised in the first guide means or in the first guide.
[0074] In one embodiment, said support member or second translatable platform comprises the first guide means or the first guide.
[0075] In one embodiment, said support member or second translatable platform is mounted translatably in the first platform, in particular it is mounted telescopically in the first platform.
[0076] In one embodiment, the first platform comprises the second guide means or the secondguide.
[0077] In one embodiment the system comprises means for selectively blocking the translation of the first container along the first axis until the second container has translated and fully entered the first zone.
[0078] In one embodiment said means for blocking comprise a protrusion on the first platform mounted for
[0079] arranging itself between the rear wall of the compartment and the rear wall of the second container, and
[0080] preventing the extraction of the first platform from the compartment by interference of parts until the second container even partially occupies the second zone.
[0081] In one embodiment, the first and / or second container are made of sheet metal.
[0082] In one embodiment the first container and / or the second container is a basket or a drawer.
[0083] In one embodiment, the furniture item comprises side walls and a rear wall that delimit a compartment accessible through a front opening, the compartment comprising said first zone, adjacent to the opening, and said second zone, further from the opening and offset with respect of the opening so that the second zone cannot be directly accessed along the first axis.
[0084] In one embodiment, in front of the first zone there is mounted a leaf which can be opened to open said opening into the compartment.
[0085] By inclination between two axes or directions the degenerate arrangement of orthogonal axes here is not comprised.
[0086] The advantages of the invention will be further clarified by preferred embodiments described below with reference to the accompanying drawings, wherein:
[0087] - Figures 1-4 show a plan diagram of a movement system with an extraction sequence of two containers;
[0088] - Figures 5-9 show three-dimensional views of an extraction sequence of two containers from a furniture item;
[0089] - Figure 10 shows an exploded view of a movement system;
[0090] - Figures 11-15 show three-dimensional views of an extraction sequence of two containers from a furniture item according to a variant;
[0091] - Figures 16-20 show respective top views of the furniture item in Figs. 11-15.
[0092] Equal numbers in the figures indicate equal or substantially equal parts. To avoid cluttering the drawings, identical members are sometimes left unnumbered.Figs. 1 to 4 show a furniture item 10 comprising side walls 12 and a rear wall 14 which delimit a compartment 18 accessible via a front opening 16. The compartment 18 comprises a first zone 18a, adjacent to the opening 16, and a second zone 18b, further away from the opening 16 and offset with respect to the opening 16 so that the second zone 18b cannot be directly accessed along the Y axis.
[0093] Inside the compartment 18, a first container 20 and a second container 60 are mounted. The first container 20 is mounted slidably along a horizontal axis Y so that it can be extracted from the compartment 18 through the opening 16. In particular, the first container 20 is slideable so as to translate from the first zone 18a towards a position extracted from the compartment 18 by passing through the opening 16.
[0094] The second container 60 is mounted slidably along a horizontal X axis orthogonal to the Y axis. In particular, the second container 60 is slideable so as to translate from the second zone 18b to the first zone 18a, and vice versa.
[0095] In one embodiment, the first container 20 has a rectangular trapezoidal plan and comprises vertical walls that delimit a loading space.
[0096] The vertical walls correspond to the sides of the right trapezoid, that is, a front wall 22 (the height), side walls 24, 26 (the minor and major base, respectively) and a rear wall 28 (the oblique side).
[0097] In one embodiment, the second container 60 has a rectangular trapezoidal plan and comprises vertical walls that delimit a loading space. The vertical walls correspond to the sides of the rectangular trapezoid, namely a rear wall 68 (the height), side walls 66, 64 (the minor and major base, respectively), and a front wall 62 (the oblique side).
[0098] The length of the walls 62, 28 and the length of the walls 68, 22 are substantially equal, but not necessarily. The first container 20 and the second container 60 are mounted to fit together along the walls 28, 62 in a complementary manner, forming an overall rectangle in plan.
[0099] The inclination of the walls 28, 62, compared for example to the walls 22, 68, is substantially the same.
[0100] In one embodiment, wheels 70 are mounted on the edges of the second container 60 closest to the rear wall 14 so that they can slide on the rear wall 14.
[0101] In one embodiment, wheels 72 are mounted on the edges of the second container 60 opposite the rear wall 14 so that they can contact and slide on the rear wall 28.
[0102] The wheels 70, 72 preferably have a vertical rotation axis (orthogonal to the plane identified by the XY axes).A push or traction member 90, such as a spring, is mounted inside the compartment 18 to push or pull the second container 60 towards the first zone 18a.
[0103] In one embodiment, the second container 60 is provided with rolling members 98, e.g. wheels, with rotation axis parallel to the X axis (fig. 10), to better slide along the Y axis.
[0104] With reference to Figures 5-10, an embodiment of the furniture item 10 and its components is illustrated. There is correspondence between the elements numbered in Figures 1 -4, so they are not repeated.
[0105] In one embodiment, the furniture item 10 of Figs. 1-4 is a module of a larger furniture item 100, as in fig. 5.
[0106] Preferably, a leaf 102 is mounted in front of the first zone 18a, whose opening lets an opening 16 to be obtained in the compartment 18 (fig. 6).
[0107] With reference to fig. 10, for the sliding along the X axis of the second container 60 the second zone 18b comprises a fixed support plane 76, which ends approximately at an edge of one of the side walls 12 which forms an edge of the opening 16.
[0108] A movable platform 78 is installed in the zone 18a which is flush with the fixed plane 76 and linearly guided by guides 80 to translate along the Y axis.
[0109] A support member 82 is translatably mounted on the movable platform 78, which can telescopically extend from the movable platform 78 along the Y-axis towards the outside of the furniture item 10. The first container 20 is mounted integrally with the support member 82, so that it can be moved away cantilevered from the movable platform 78 when the support member 82 extends relative to the movable platform 78.
[0110] In one embodiment, the movable platform 78 has a protrusion 84 that fits between the rear wall 14 and the rear wall 62 when the first and second containers 20, 60 are placed side by side along the X-axis within the compartment 18.
[0111] OPERATION
[0112] At rest (fig. 1 , 5 and 6) the first and second containers 20, 60 are both contained in the compartment 18 and are placed side by side along the X axis. The first container 20 occupies the first zone 18a and the second container 60 occupies the second zone 18b.
[0113] For example, the first container 20 can be extracted manually along the Y axis to drag it outside the compartment 18 (fig. 2 and 7). With reference to the preferred means of fig. 10, the support member 82 translates relative to the movable platform 78 along the Y axis towards the outside of the compartment 18 to correspondingly move the first container 20. The movable platform 78 has not yet moved because it is blocked by the interference between the projection 84 and the rear wall 62.When the first container 20 has completely cleared the first zone 18a, the latter is occupied by the second container 60 which arrives there by translating along X under the action of the member 90. Unlike what is shown in fig. 2, if the member 90 is a spring, it ensures constant contact between the first and second containers 20, 60. At the end of the stroke (fig. 3 and 8) the second container 60 has queued up behind (at the tail of) the first container 20, so that the first and second containers 20, 60 are aligned along the Y axis, the walls 28, 62 are facing and aligned, and the wheels 72 are in contact with the wall 28. In this position the interference between the protrusion 84 and the rear wall 68 is eliminated, because the second container 60 has moved sufficiently. Therefore the assembly of the first and second container 20, 60 can be further moved away from the compartment 18 along the Y axis to also extract the second container 60 from the compartment 18.
[0114] With reference to the preferred means of fig. 10, the movable platform 78 is now free to translate relative to the rear wall 14 along the Y-axis towards the outside of the compartment 18 to correspondingly and integrally move the first and second containers 20, 60 (figs. 4 and 9), which both end up outside the compartment 18. The movable platform 78 translates on the guides 80 along the Y-axis towards the outside of the compartment 18 .
[0115] To reinsert the first and second containers 20, 60 back into the compartment 18, the first container 20 is manually pushed towards the rear wall 14 along the Y-axis. Consequently, the second container 60 returns into the compartment 18 in the first zone 18a.
[0116] By pushing the first container 20 further, the second container 60 reaches the end of its stroke in the first zone 18a, and the wheels 70 abut against the rear wall 14. From here on, the push of the wall 28 against the wheels 72 causes the wheels 72 to slide along and on the wall 28. Therefore, the push along the Y axis on the first container 20 now has two effects: it brings the first container 20 completely into the first zone 18a and pushes the second container 60 along the X axis until it returns to the second zone 18b.
[0117] Note the advantageous function of the protrusion 84. It allows the second part of the telescopic structure, i.e. the movable platform 78, to be extracted from the compartment 18 only when the first container 20 is out of the compartment 18 and only when the second container 60 has completely passed from the second zone 18b to the first zone 18a. This constraint eliminates jams and prevents, for example, the second container 60, while moving, from falling into the void behind the movable platform 78.
[0118] The traction or push member 90 is one embodiment of means for moving the second container 60 queued up behind the first container 20 when the first container 20 is extractedfrom the compartment 18 along the Y-axis. Another embodiment of such means is shown in figs. 11 et seq. (the containers 20, 60 are the same as in figs. 1-4).
[0119] The first container 20 and the second container 60 are coupled so that they interact with each other by converting a pull on the first container 20, directed along the Y-axis away from the rear wall, into a force on the second container 60 directed along the X-axis to move the second container 60, which is now adjacent along X to the first container 20, from the second zone 18b to the first zone 18a. In particular, the first container 20 and the second container 60 are permanently connected so that by extracting the first container 20 along the Y-axis the latter pulls the second container 60 along the X-axis, moving it from the second zone 18b to the first zone 18a.
[0120] Such a connection between the first container 20 and the second container 60 can be made in many ways.
[0121] In one embodiment, the second container 60 comprises an L-shaped guide 200 interacting with a fixed member 250, e.g. a pin, mounted, e.g. vertically, on the first container 20. The L-shaped guide 200 has a central vertex 210 (where the two "legs" of the L meet).
[0122] In particular, the member 250 is placed at the vertex formed by the walls 24, 28 (the wall 24 is the shorter side wall of the two and the one closest to the second container 60).
[0123] The L-shaped guide 200 is formed of a section 202 and a section 204, where the section 202 extends along and parallel to the wall 66 (or in general parallel to the Y axis); and the section 204 extends along and parallel to the wall 62 (or in general along a bisector of the angle formed by the Y and X axes). The two sections 202, 204 are joined at the central vertex 210.
[0124] The member 250 is constrained to the L-guide 200 so as to slide confined within and along the entire length of the L-guide 200, i.e. along the sections 202, 204, when the first container 20 and the second container 60 move relatively.
[0125] For this purpose, for example, the L-shaped guide 200 may be a grooved rail or a U-shaped profile, and the member 250 a slider adapted to travel thereon. In another embodiment, the member 250 is an eyelet and the L-shaped guide 200 is a tensioned wire threaded into it. In another embodiment, the L-shaped guide 200 is a T-shaped guide and the member 250 a C-shaped slider slidably coupled to it.
[0126] OPERATION
[0127] At rest (fig. 11 and 16) the first and second containers 20, 60 are placed side by side inside the compartment 18 along X, as in fig. 1. The member 250 is located at one end ofthe section 202, maximally close to the wall 14.
[0128] By extracting the first container 20 along the Y axis to take it out of the compartment 18 (fig. 12, 16 and 17), the member 250 translates relative to the section 202 until it reaches the central vertex 210 (fig. 12 and 17).
[0129] Continuing the extraction of the first container 20, the member 250 passes the central vertex 210 and mates with the section 204. Now the movement of the first container 20 along the Y axis pushes the member 250 along the section 204. The inclination of the section 204 with respect to the Y axis generates a reaction force between the member 250 and the section 204 which pushes the second container 60 along X from the second zone 18b towards the first zone 18a bringing the second container 60 queued up behind the first container 20.
[0130] When the member 250 has reached the end of the section 204, the first container 20 has completely cleared the first zone 18a, and first zone 18a is occupied by the second container 60 (fig. 13 and 18).
[0131] Once the first container 20 and the second container 60 are aligned along the Y-axis, they can slide along the Y-axis to be both extracted from the compartment 18 (fig. 20 and 15).
[0132] To bring the containers 20, 60 back into the compartment 18, the first container 20 is pushed along Y towards the rear wall 14. The containers 20, 60 move with motions inverse to the previous ones and return side by side into the compartment 18. In particular, the inclination of the section 204 with respect to the Y axis generates a reaction force between the member 250 and the section 204 which pushes the second container 60 along X from the first zone 18a to the second zone 18b (towards the right in the drawings) bringing the second container 60 into the second zone 18b.
[0133] Note that advantageously such a connection between the first container 20 and the second container 60 allows the movements of the containers 20, 60 to be reversed by pushing rather than pulling the container 20.
[0134] With the same effects described, the L-shaped guide may alternatively be mounted on the first container 20 along the wall 24 and the back 28; and the member 250 can be mounted on the second container 60 in correspondence with the angle formed by the walls 62, 66.

Movement system according to claim 1, wherein the first and second containers comprise respective portions which areconfigured to contact each other when the second container is queued up behind the first container, andconfigured so that said push on the first container causes a relative sliding between said portions and consequently a translation of the second container, inside the compartment along the second axis, which moves the second container towards the second zone to cause it to abandon its position in the first zone queued up behind the first container.
3. Movement system according to claim 2, whereinthe first container comprises a first vertical plane which is- inclined with respect to the first axis and- facing said rear wall, andthe second container comprises a second vertical plane which is- inclined in a complementary manner to the first inclined plane and- facing the first inclined plane;the first and second vertical planes being adapted to interact with each other, when the second container is queued up behind the first container and a thrust is exerted on the first container along the first axis towards the rear wall, so that there is a relative sliding of said vertical planes and consequently a translation of the second container inside the compartment along the second axis towards the second zone.
4. Movement system according to any preceding claim, wherein the first and second containers comprise vertical walls that delimit a loading space in the shape of a right-angled trapezium,said walls being arranged like the sides of a right-angled trapezium and giving the first and second container a right-angled trapezium plan with a respective oblique side,the first vertical plane and the second vertical plane being made in correspondence with, or by the inclination of, the oblique sides of said trapeziums.
5. Movement system according to claim 4, wherein the first and second vertical planes coincide with the vertical walls constituting the oblique sides of said trapeziums, and such vertical walls are mounted facing each other and able to slide relatively.
6. Movement system according to claim 3 or 4 or 5, wherein the second container comprises rolling members mounted so as to be able to slide on the first vertical plane.
7. Movement system according to any preceding claim, comprising means for automatically moving the second container along the second axis and bringing it queued up behind the first container.
8. Movement system according to claim 7, wherein said means for moving comprise an elastic member, e.g. a spring, mounted to push or pull the second container along the second axis.
9. Movement system according to any preceding claim, whereinthe second zone is provided with a fixed support plane on which the second container can slide back and forth along the second axis to move from the second zone to the first zone and vice versa; andthe second container comprises rolling members with a horizontal rotation axis to slide on the fixed plane.
10. Movement system according to any preceding claim, comprising a telescopic structure for moving the first and second containers together and integrally away from the compartment when the second container is in the first zone and queued up behind the first container.
11. Movement system according to any of claims 2 to 10, wherein at least one of said portions comprises or consists of an inclined plane that is oriented and extends parallel to a bisector of the angle formed by the first and second axes.
12. Movement system according to claim 11, wherein both said portions comprise or consist of an inclined plane which is oriented and extends parallel to a same bisector of the angle formed by the first and second axes.
13. Movement system according to any of claims 2 to 10, whereinone of said portions comprises or consists of an inclined plane which is oriented and extends parallel to a bisector of the angle formed by the first and second axes, andthe other of said portions comprises or consists of a member mounted integral with the relative container and slidable along said inclined plane.
14. Movement system according to any preceding claim, comprising a horizontal L or V-shaped guide mounted on one of the first or second container,the other container comprising a slider member slidingly coupled with the guide, the guide and the slider member being dynamically coupled so thatsaid push on the first container determines the sliding of the fixed member inside the guide andsuch sliding, together with the interaction of the slider member with the walls of the guide, induces said force on the second container.
15. Movement system according to any preceding claim, comprising a horizontal L or V-shaped guide mounted on one of the first or second container,the other container comprising a slider member slidingly coupled with the guide, the guide and the slider member being dynamically coupled so thata pull to extract the first container from the compartment causes the slider member to slide inside the guide andsuch sliding, together with the interaction of the slider member with the walls of the guide, induces a force on the second container which drags it from the second to the first zone.
