Description

Disassembleable hinge and piece of furniture using the same .
The present invention refers to a disassembleable hinge according to the preamble of claim 1.
The present invention relates also to a piece of furniture or cabinet having a door and a frame using the disassembleable hinge according to claim 1.
A lot of apparatus comprises doors equipped with hinges and handles for accessing the inner compartments .
According to the installation of this apparatus, it may be preferable that the door opens in one specific direction; therefore, when designing these apparatus, it is also necessary to consider these requirements.
A first and obvious solution to solve the problem consists in mounting the hinges and the handles on the doors when installing the apparatus: the hinges will be applied to the door side in order to keep the desired opening direction.
This solution is very demanding for the installation personnel both in terms of care and time.
Furthermore, the opening direction of the door cannot be easily changed after the installation (for example because of new needs of the user) ; in general this task has to be carried out by qualified personnel.
A second method for the solution of the above mentioned problem consists in producing different apparatus according to the opening direction of the door.
This solution is disadvantageous due to the high production and storage costs.
WO2006/136939 describes a disassembleable handle comprising a fixed assembly susceptible of being applied to a door, and a movable rotably assembly according to a rotation axis of the hinge mounted on the fixed assembly; the fixed assembly comprises a pivot which defines a rotation axis of the handle; the movable assembly comprises at least two elements rotably mounted together according to a rotation axis of the movable assembly, which are parallel to the rotation axis of the handle; within the movable assembly there are seats for the pivot. The handle has a first operating configuration wherein the elements of the movable assembly are reciprocally rotated in such a way as to trap the pivot, and a second operating configuration wherein the elements of the movable assembly are rotated in such a way as to release the pivot.
However, if the apparatus upon which the above mentioned handle is mounted is equipped with doors for containing an air pressure, such as for instance the air handling units (AHU) , it is necessary to allow the air pressure to flow at the moment of the opening of the door through the handle, avoiding in the same way that the door slams for effect of the pressure, in order to reduce the risk of getting the door on the face at high speed.
The object of the present invention is to describe a disassembleable hinge which overcomes the above described drawbacks and solves the above described problems.
According to the present invention a disassembleable hinge is realized as claimed in claim 1.
According to the present invention is also realized a cabinet of an apparatus comprising a hinge object of the present invention according to claim 10.
The invention will be now described with reference to the attached drawings, which illustrate a non limiting form of implementation, wherein :
- figures 1-3 show respective perspective views of a hinge object of the present invention;
- figures 4-9 show section views of respective configurations of the hinge object of the present invention in a first embodiment;
- figures 10-15 show section views of respective configurations of the hinge object of the present invention in a second embodiment .
Figures 1, 2 and 3 describe a disassembleable hinge according to the present invention in a first embodiment, which comprises a fixed assembly A and a movable assembly comprising a first element B and a second element C.
Fixed assembly A is susceptible of being applied to a frame and the movable assembly B+C is susceptible of being applied to a door; in particular, first element B is adapted for being directly associated to the door to be handled (and in detail, opened, closed and if necessary removed) .
The movable assembly B+C is rotably mounted on first fixed assembly A according to a rotation axis X of the hinge; for this reason, the fixed assembly comprises three pivots, integral within a component realized in a unique piece, which define said rotation axis X of the hinge; in the illustrated examples, there is an intermediate pivot A2 and two lateral pivots A3; said pivots are supported by a pair of arms Al of the assembly A, which are coupled to a closing plate of assembly A; lateral pivots A3 protrude from arms Al .
Assembly A is fastened to the frame, in particular to an upper part of the frame, by means of a pair of screws inserted within two elongated holes A4 , obtained in the fastening plate of assembly A.
Elements B and C of the movable assembly are rotably connected together according to a rotation axis Y which is parallel to rotation axis X of the hinge .
Seats are obtained within elements B and C in positions B2 (B2I, B2L) and C2 for pivots A2 and A3; in particular, element C comprises an arm, and seat C2 is obtained for an ending part of said arm for the intermediate pivot A2. Element B also comprises two intermediate arms and two lateral arms; upon an end of the intermediate arms, two intermediate seats B2I are obtained for the intermediate pivot A2 , while at the end of the lateral arms, two lateral seats B2L are obtained for the two lateral pivots A3. Four arms of assembly B are united to a closing plate of assembly B. Assembly B is united to the door through three screws inserted in three elongated holes B4 obtained in the closing plate of assembly B .
Elements B and C comprise reciprocal mounting means; in particular, the arms of element C comprise two protrusions CI (up and down) and the two intermediate arms of element B have two corresponding recesses or cavities B3 for the two protrusions CI; as shown in figures, the. mounting means, that are protrusions and recesses, are housed in the area of the se,ats; protrusions CI are inserted in recesses B3 and remain trapped ■there, contemporarily allowing the reciprocal rotation of elements B and C. In fact, when the hinge is mounted on the door, element C rotates around element B which stays stationary.
The movable assembly comprises also an intermediate release system, susceptible of allowing a first partial opening of the door without releasing it totally from the frame.
As shown in figure 4, the intermediate release system comprises a supporting plane 10, slidably mounted within the body of element B and oriented in a direction orthogonal to the one detected by axis X and Y.
To supporting plane 10 is fastened a pin 11, susceptible of being operated by a user; pin 11 extends orthogonally with respect to supporting plane 10 and protrudes outside of element B.
A spring 12 is positioned parallely to supporting plane 10 and is constrained at its first end to the body of element B and at its second end to pin 11. Spring 12 exerts a thrust force of pin 11 and therefore of supporting plane 10 in a first operating position.
In this first operating position, a front part 10 of supporting plane 10 is positioned in front of intermediate seats B2I and of lateral seats B2L.
In a second operating position, kept as unstable through a force exerted by a user on pin 11, front part 10a of supporting plane 10 is retracted inside the body of element B releasing the part in front of the intermediate and lateral seats B2I and B2L.
In the first operating position, supporting plane 10 prevents the intermediate pivot and the lateral pivots A2 , A3 from exiting from intermediate and lateral seats B2I, B2L, allowing anyway a slight opening of the door, susceptible of allowing the exit of the air possibly under pressure between the door upright and the assembly formed by the door itself and element B.
Therefore, the door cannot get on the face of the user, but it is retained in position properly by the contrast between pivots A2 , A3 and supporting plane 10.
The hinge object of the present invention can therefore be in three operating positions. In all of these three operating positions elements B and C are strongly constrained the one to the other.
In a first operating configuration, elements B and C are reciprocally rotated in order to allow the entrapment of the intermediate pivot A2 of assembly A. Therefore, the movable assembly and the door associated to it can rotate around axis X of the hinge; in a second operating condition elements B and C of the movable assembly are reciprocally rotated in order to release pivot A2 ; therefore, the movable assembly and the door associated to it can be detached from the fixed assembly and the door can be either rotated around another hinge or removed.
The second operating condition of the hinge is subject to the second operating condition of supporting plane 10, that is to the contemporary action on pin 11 by the user.
In the third operating condition elements B and C, as well as in the above described second operating condition of the hinge, are reciprocally rotated in order to release pivot A2. However, in the third operating condition of the hinge, the contextual position of supporting plane 10 in its first operating configuration, prevents the complete release of the fixed and movable assembly, through a contrast between pivots A2 , A3 and the supporting plane as previously described.
Element C comprises a handle in which a recess C3 is obtained in the handle itself for a latch C4 susceptible of locking elements B and C together when the movable assembly is in the first operating configuration, that is when the handle of element C is adjacent to the closing plane of element B.
Latch C4 can be rotated through the use. of an Allen key (not shown in the attached figures) ; as an alternative to latch C4 , a keylock can be integrated within the handle .
The shape and the section of seats C2 and of protrusions CI is important; the outer section of protrusions CI is substantially circular, the section of seats C2 is substantially U-shaped, with rounded angles; the axis of protrusions CI corresponds to the axis of the movable assembly; the symmetry axis of seats C2 is parallel and displaced with respect to the axis of protrusions CI .
The section of seat C2 is higher than the section of the pivot, and in this way its lateral surface acts on the lateral surface of the pivot with a variable contact.
It follows that the distance between rotation axis X of the hinge and rotation axis Y of the movable assembly depends on the reciprocal angular position of the elements of the movable assembly; the surface of the seat acts on the pivot such that the rotation of element C with respect to element B causes a displacement of rotation axis Y of the movable assembly.
Between the pivot and the movable assembly, a force F is then created, which has a component Fy, oriented in a direction parallel to a closing direction of the door against the frame. Component Fy of force F decreases with the increase of the rotation of the handle until the component is not cancelled in correspondence to a rotation of it equal to 900.
As shown in figure 4, the hinge is in the first operating configuration. A gasket 20 positioned between the door and upright 21 is compressed and prevents the eventual air under pressure inside the apparatus from exiting.
At the opening of the handle, through the rotation of it around rotation axis Y, pivot A2 is released from seats B2I, B2L, B3 and the door can open allowing the air to exit (figure 5, arrow AIR representing -the air) and thus bringing the hinge object of the present invention in the third operating configuration.
Therefore, through the action on pin 11, supporting plane 10 is retracted inside the body of element B (figure 6) and the door can therefore totally open (figure 7) .
When supporting plane 10 overtakes pivot A2 , the supporting plane in absence of the force exerted by a user on pin 11, returns in its first operating configuration.
During the closing of the door., as shown in figures 8 and 9, pivot A2 meets the front part 10a of supporting plane 10, which in absence of the force exerted by a user is returned in its first operating configuration.
However, both pivot A2 and supporting plane 10 have respective beveled parts. In particular, the beveled parts of pivot A2 and of supporting plane 10 are arranged such that during the reclosing of the door enter reciprocally in contact.
The beveled tip of the part 10a of supporting plane 10, meets therefore the beveled part of the pivot and slides along a plane inclined formed by it. For the effect of the force exerted by a user during the closing of the door, opposed forces are created along the inclined plane which cause spring 12 to compress, retracting supporting plane 10 within element B toward its second operating configuration. The hinge object of the present invention is then capable of reclosing without intervention on pivotlO.
As soon as supporting plane 10 has overtaken pivotA2, supporting plane 10 for effect of the force exerted by spring 12 returns again in the first operating configuration.
In figures 10-13 it is shown . a second embodiment of the hinge object of the present invention .
The second embodiment differentiates from the first embodiment described up to this point as fixed assembly A comprises also a locking element 40, susceptible of allowing the locking of the door in a position of intermediate opening, or in a third operating condition, in which it results to be partially open with respect to the upright, allowing, as in the case of the first embodiment, the air possibly under pressure between the door upright and the assembly formed by the door itself and element B to exit, without the door being free to completely open and hitting then a user.
Furthermore, the second embodiment of the hinge differs from the previous one for the absence of a movable supporting plane to realize the intermediate release system. In this case, on the other hand, the intermediate release system comprises further then locking element 40, also a step 41, positioned on movable assembly B and, more in detail, on the arms of element B itself. This step 41 is configured for removably engaging with locking element 40.
In detail, as it can be noticed in figure 10, th locking element 40 comprises a L-shaped body having a first and a second portion oriented between them at 90°; whereas the first portion is for its maximum part fixed, or integrally realized with fixed element A, and faced to the door upright, the second portion protrudes orthogonally with respect to the upright itself, along a direction orthogonal with respect to the direction detected by axis Y.
Second portion 40b of locking element 40 comprises an arrow-shaped ending portion, having an oblique side 40c which identifies a tapering in its end and a portion having a higher thickness; in this portion having a higher thickness it is highlighted a step recess 40d, faced towards element. B, and susceptible of fitting with step 41 through a flexion of the second portion.
As noticed in figure 10, at the opening of handle or element C, the hinge is in the first operating configuration. A gasket 20 positioned between the door and upright 21 is compressed and prevents the air possibly under pressure inside the apparatus from exiting.
At the opening of the handle, through the rotation of it around rotation axis Y, pivotA2 is released from seats B2I, B2L, B3 and the door can open allowing the air to exit (figure 11, arrow AIR representing the air) and bringing then the hinge object of the present invention in the third operating configuration.
In the third operating configuration step recess 40d enters in contrast with step 41 positioned on element B, and therefore the door opens only partially.
At this point, a user, as shown in figure 1, must exert a flexion force F__l of the second portion of locking element 40, in order to bring the door to a complete opening.
In order to do this, this force F_l must have at least a component orthogonally directed toward axis Y and sufficient for flexing the second portion of locking element 40 of a length sufficient for overtaking the length of step 41.
After the getting over step 41, the second portion of locking element 40 returns again in the position orthogonal .with respect to the first portion (figure 13) .
During the closing, as shown in figure 14, step 41 firstly runs into the inclined side of the ending part of the second portion of locking element 40. This inclined side is configured such that a force of pressure of the door against the upright causes a reaction force on the second portion of the locking element enough for causing a new flexion outwards; if the force applied is enough, the door and in particular step 41 of movable assembly B+C overtake step recess 40d and the second portion recovers a direction orthogonal with respect to the first portion of locking element 40.
The complete closing of the door (first operating configuration) is again reached by rotating element C and in particular the handle in a position adjacent to the closing plane of element B. It is then clear that the first and the second embodiment of the present invention can be combined between them for supplying the hinge object of the present invention with a first, second intermediate closing (or opening) system.
The advantages of the hinge object of the present invention are clear in the light of the previous description. In particular, it allows to realize a closing element of a door of a cabinet of an apparatus subject to an inner pressure higher than the outer one, and prevents that accidentally, because of the pressure gradient very elevated, the door can slam violently against the user.
The intermediate closing or opening system allow therefore to define a limited area or sector wherein the movable assembly can freely move with respect to the fixed assembly without allowing the complete opening of the door and therefore without allowing the complete disengagement of the movable assembly with respect to the fixed assembly.
The hinge object of the present invention allows also the reclosing or repositioning of the simple door, without the user having to intervene again on the pin.
To the hinge up to here described can be applied many variants, integrations or changes obvious for an expert in the art without exiting from the protective scope given by the attached claims .
