Description

System for assembling removable elements.
TECHNICAL FIELD
The invention refers to a system for assembling removable elements, in particular elements suitable to form frameworks for shelvings, furniture and temporary walls. BACKGROUND ART
There are various systems for assembling removable elements for example forming a framework for shelvings, furniture and temporary walls.
One of the drawbacks most commonly observed in these known assembly systems regards the alignment between each pair of removable elements in the assembly step.
The positioning of each element with respect to the subsequent one is actually difficult to control and the rotation of one with respect to the other during connection always entails an angular positioning error, thus making the finished assembled framework aesthetically unappealing and potentially unstable.
An interesting solution is outlined by W0198901 1043 which discloses an assembly device for assembling dismountable or modular elements essentially constituted by first and second assembly bodies. The assembly bodies differ from each other solely by their central locking portions that have respective male and female bayonet and sloping ramp couplings at first ends thereof. At least the first assembly body is such that relative rotation between the two assembly bodies for the purpose of the bayonet coupling also automatically locks the first assembly body in the associated hollow section bar.
WO 2013/055292 A1 discloses a connector system of a structural frame comprising a socket device and a plug device that can be coupled to the socket device. The socket device includes an outer housing and a socket member in the socket housing, the socket member having a socket hole of non-circular cross-section. The plug device comprises a plug body and a coupling sleeve slidably and rotatably fitted onto the plug body that includes an exposed plug end portion axially projecting out of the coupling sleeve to fit into the socket hole of the socket member. The plug body and the coupling sleeve include axial cam members engaging each other to cooperate upon a rotation of the coupling sleeve for an axial displacement of the coupling sleeve between the release position and a coupling position.
US 2015/300391 A1 discloses a system suitable for the assembly of removable elements comprising a male cylindrical end of a first mechanical element, two female tubular cylindrical ends of a second mechanical element and an additional male cylindrical end. The cylindrical ends are arranged coaxially along an axis z representing their common central axis. The male cylindrical ends have locking grooves hollowed in their outer surface parallel to the axis z and over a portion of their length starting from their free end. Each of the locking groove ends located opposite the free ends of the male cylindrical ends have a partially spherical cavity of a greater depth also hollowed in the outer surface. The female tubular cylindrical ends are bored on the side with a through-openings inside of which are arranged at least a mobile locking element able to protrude inside the female tubular cylindrical ends in the locking grooves of the male cylindrical ends when these latter are engaged in the female tubular cylindrical end according to a suitable ortho-radial angle. At least a locking ring is mounted on the outer surface of a female tubular cylindrical end opposite the through-opening. Each locking ring has an inner surface with a recess with variable depth enables the locking/unlocking of the locking element against the locking grooves. As another embodiment, the locking groove of the additional male cylindrical end has two segments extending axially, and three segments partially annular and orthogonal to the first two. An additional cavity of partially spherical shape is hollowed at the end of the fifth segment which accommodates an additional mobile locking element. The second segment extending axially is used as an angular guide for the additional mobile locking element. But for coupling the additional male cylindrical end to the tubular intermediary part a rotation is required.
Also EP 0167499 A2 and US 3480310 A disclose systems suitable for the assembly two parts which do not require a rotation of the parts to be connected.
However, there arises the need for a new improving connection system that enables the axial coupling and de-coupling between the two removable elements without having to rotate one with respect to the other. DISCLOSURE OF INVENTION

These and other objects are attained by the system for assembling removable elements according to the invention, comprising a first locking device, a second locking device, a third locking device and an angular connector.
The first locking device has a hollow or solid central locking element extending along the longitudinal axis thereof. The central locking element of the first locking device has - on the wall - at least one first guide having a longitudinal axis parallel to that of the central locking element. An end of the first guide starts from the free end of the central locking element. The central locking element of the first locking device also has at least one second guide having a longitudinal axis orthogonal to that of the central locking element extending for at least 90°. The second end of each first longitudinal guide is in communication with an end of each second orthogonal guide and each pair of guides, arranged to form an L shape, delimits a fin.
The second locking device has an externally cylindrical hollow central locking element extending along the longitudinal axis thereof. The hollow central locking element of the second locking device has - on the wall - at least one guide extending for at least 90°. Each guide has a longitudinal axis orthogonal to that of the central locking element. The second locking device has at least one guide element. The central locking element of the second locking device houses - therein - the central locking element of the first locking device. The central locking element of the second locking device has an inner section equivalent to the external one of the central locking element of the first locking device.
The third locking device consists in a hollow sleeve housing - therein - the central locking element of the second locking device and it rotates thereon. Externally, the hollow sleeve has faces for facilitating the manual rotation thereof. The third locking device is formed by at least two parts and it is provided with at least one pin projecting towards the internal.
An end of each central locking element of the first and of the second locking device is fixed on a face of a support. A gripping element is fixed on an opposite face of the support. The gripping element with a removable element consists in a unit inserted into the inner cavity of the removable element and connected thereto by pressing or coupling. The gripping element of the first and of the second locking device can be female-shaped or male-shaped or threaded and be connected to a male-shaped or female-shaped or threaded gripping element of the angular connector.
Each guide element of the second locking device is male-shaped and it can be fixed on the inner wall of the central locking element thereof. Each guide element is housed in the end of a first longitudinal guide of the central locking element of the first locking device.
In another preferred embodiment, each guide element is present on the support of the second locking device inside the central locking element. Each guide element can be male-shaped and it can be housed in the end of a first longitudinal guide of the central locking element of the first locking device or in at least one cavity obtained in the free end of such central locking element.
Each guide element present on the support of the second locking device in the central locking element can even be female-shaped. Each female-shaped guide element houses an equivalently-shaped male-shaped projection obtained in the free end of the central locking element of the first locking device.
In another preferred embodiment, the central locking element of the first locking device has - in the outer wall - at least one projecting edge constituting a guide element with longitudinal axis parallel to that of the central locking element of the first locking device. Such edge of the first locking device is housed in a groove obtained in the inner wall of the central locking element of the second locking device.

The cube-shaped angular connector can enable the connection between at least two removable elements even with angles different from 90° when a rotating element is present therein. The removable elements fixed on the bases of the rotating element are coaxial, while the remaining removable elements fixed on the remaining bases of the cube-shaped angular connector will rotate together with it.
The connection system subject of the invention enables obtaining greater versatility of use given that it allows obtaining the axial coupling and de-coupling between the two removable elements without having to rotate one with respect to the other. As a matter of fact, the only element that rotates is the third locking device.
Another advantage of the invention lies in enabling the easy coupling and de-coupling of intermediate or terminal parts of previously formed two-dimensional and three- dimensional structures without involving and removing structural elements.
Another advantage, using the aforementioned cube-shaped angular connector with a rotating element, lies in the possibility of assembling several removable elements even at angles different from 90°. BRIEF DESCRIPTION OF DRAWINGS

BEST MODES FOR CARRYING OUT THE INVENTION
In a first embodiment, the system for assembling removable elements according to the invention comprises a first locking device 1 formed by a central locking element 1 .1 extending along the longitudinal axis thereof, by a support 1 .2 and a gripping element 1 .3 with a first removable element. In the preferred embodiment described herein, the central locking element 1 .1 consists of a hollow cylindrical shaft.
An end of the central locking element 1 .1 is fixed on a face of the support 1 .2 and the gripping element 1 .3 is fixed on an opposite face of the support 1 .2. The gripping element 1 .3 consists in a cubic body pressure-inserted into the inner cavity of the first removable element. The outer section thereof is slightly smaller than the inner section of the first removable element.
The central locking element 1 .1 of the first locking device 1 has - on the wall - two opposite guides 1 .4, in form of slots, arranged diametrically having a longitudinal axis parallel to that of the central locking element 1 .1 , whose one end starts from the free end of the central locking element 1 .1 . The central locking element 1 .1 of the first locking device 1 further has - on the wall - two diametrically opposite second guides 1 .5 having a longitudinal axis orthogonal to that of the central locking element 1 .1 , extending for at least 90°. The second end of each first longitudinal guide 1 .4 is in communication with an end of each second orthogonal guide 1 .5. Each pair of guides 1 .4, 1 .5, arranged to form an L shape, delimits a fin 1 .6.
The system for assembling removable elements comprises a second locking device 2 formed by an externally cylindrical hollow central locking element 2.1 , a support 2.2 and a gripping element 2.3 with a second removable element. An end of the central locking element 2.1 is fixed on a face of the support 2.2 and the gripping element 2.3 is fixed on an opposite face of the support 2.2. The central locking element 2.1 has dimensions such to be able to house - therein - the central locking element 1 .1 of the first locking device 1 .
The central locking element 2.1 of the second locking device 2 has - on the wall - two diametrically opposite guides 2.4 having a longitudinal axis orthogonal to that of the central locking element 2.1 , extending for at least 90°.
The second locking device 2 is provided with two elements of the guide element 2.5 diametrically fixed on the inner walls of the central locking element 2.1 . Each guide element 2.5 is male-shaped and it has two opposite sides arranged according to axes parallel to the longitudinal axis of the central locking element 2.1 .
The system for assembling removable elements further comprises a third locking device 3 consisting in a hollow sleeve 3.1 formed by two parts, from each one of which a pin 3.2 projects towards the internal. The two pins 3.2 are opposite. The hollow sleeve 3.1 is externally parallelepiped-shaped to enable the easy manual rotation thereof. It has two bases 3.3 in each one of which a circular hole 3.4 is obtained. The edges of the holes 3.4 slide on the outer surface of the central locking element 2.1 of the second locking device 2.
When assembling, the gripping element 1 .3 of the first locking device 1 is inserted into the first removable element and the gripping element 2.3 of the second locking device 2 is inserted into the second removable element.
The central locking element 1 .1 of the first locking device 1 is then inserted longitudinally into the central locking element 2.1 of the second locking device 2. This enables obtaining the axial alignment between the two removable elements but not the angular one. This occurs by rotating the second locking device 2 until the ends of the two first longitudinal guides 1 .4 of the central locking element 1 .1 of the first locking device 1 touch the opposite parallel sides of the two elements of the guide element 2.5 arranged diametrically in the central locking element 2.1 of the second locking device 2. Considering that the two first longitudinal guides 1 .4 of the central locking element 1 .1 of the first locking device 1 have axes parallel to those of the central locking element 1 .1 and that the two elements of the guide element 2.5 of the central locking element 2.1 of the second locking device 2 have two opposite sides arranged according to axes parallel to the longitudinal axis of the central locking element 2.1 , angular alignment is obtained between the two removable elements. Further rotations of a locking device with respect to the other are also hindered.
The first opposite longitudinal guides 1 .4 of the central locking element 1 .1 of the first locking device 1 have dimensions such not only to house the two guide elements 2.5 of the second locking device 2 but also enable the sliding of the pins 3.2 of the third locking device therein.
Thus, the first longitudinal guides 1 .4 of the central locking element 1 .1 of the first locking device 1 have two functions: enabling the sliding of the pins 3.2 therein and enabling the angular alignment thanks to the housing of the guide elements 2.5 in the free ends thereof.
When the central locking element 1 .1 of the first locking device 1 is inserted into the central locking element 2.1 of the second locking device 2, the first two longitudinal guides 1 .4 of the central locking element 1 .1 firstly receive the pins 3.2 of the third locking device and then they house the two guide elements 2.5 of the second locking device 2. At this point, each pin 3.2 of the third locking device 3 is at the end of each second orthogonal guide 1 .5 of the central locking element 1 .1 placed in communication with the first longitudinal guide 1 .4. The second orthogonal guides 1 .5 of the central locking element 1 .1 and the orthogonal guides 2.4 of the central locking element 2.1 of the second locking device 2 are superimposed when the central locking element 1 .1 ends its travel.
Upon rotating the third locking device 3 with respect to the remaining locking devices 1 , 2, each pin 3.2 translates from the end of the second orthogonal guide 1 .5 placed in communication with the first longitudinal guide 1 .4, at the other end of the second orthogonal guide 1 .5. Simultaneously, each pin 3.2 translates from the first end of the orthogonal guide 2.4 of the central locking element 2.1 of the second locking device 2 to the second end of the orthogonal guide 2.4 ending up engaging a fin 1 .6 of the first locking device 1 . This enables obtaining a bayonet-coupling between the three locking devices 1 , 2, 3 and, thus, between the two removable elements.
The disassembly of the two removable elements simply requires rotating the third locking device 3 in the reverse direction. The pins 3.2 then translate from the second to the first end of the two orthogonal guides 1 .5, 2.4. At this point, the pins 3.2 are at the first longitudinal guides 1 .4 of the first locking device 1 . It is thus sufficient to move the first locking device 1 away from the second locking device 2 by sliding the pins 3.2 in the first guides 1 .4 up to the complete separation of the two locking devices 1 , 2 and of the corresponding removable elements.
Locking devices 1 , 2 having the gripping elements 1 .7, 2.6 fixed to the face of the support 1 .2, 2.2, opposite to the one on which the central locking element 1 .1 , 2.1 is fixed, are used in order to obtain a 90° connection between the two removable elements. Each gripping element 1 .7, 2.6 of the locking devices 1 , 2 is male-shaped and it consists in a pin at whose free end the two fins are fixed. Both locking devices 1 , 2 end up connected to a known hollow cube-shaped angular connector 4, shown in Figs. 25, 29. The hollow angular connector 4 has - in each of the six faces - a female- shaped gripping element consisting in a slot 4.1 with dimensions slightly larger than the dimensions of the fins of each gripping element 1 .7, 2.6.
When assembling, a first removable element is connected - through a gripping element 1 .3 - to a first locking device 1 and a second removable element is connected - through a gripping element 2.3 - to a second locking device 2. The male- shaped gripping element 2.6 of the second locking device 2 is inserted into a slot 4.1 of a face of the hollow angular connector 4. The rotation of the hollow angular connector 4 causes the engagement of the fins of the male-shaped gripping element 2.6 on the hollow angular connector 4, thus obtaining a bayonet-coupling between the latter and the second locking device 2.
The male-shaped gripping element 1 .7 of the first locking device 1 - to which the second removable element is connected through a second locking device 2 - is thus inserted into a slot 4.1 of a second face, orthogonal to the first, of the hollow angular connector 4. The rotation of the first locking device 1 causes the engagement of the fins of the male-shaped gripping element 1 .7 in the hollow angular connector 4, thus obtaining a bayonet-coupling between the hollow angular connector 4 and the first locking device 1 . This enables positioning the second removable element at 90° with respect to the first removable element.
As shown in Figs. 30, 31 , a hollow cube-shaped angular connector 5 which enables the connection between two removable elements can be used even at angles different from 90°. Such angular connector 5 has a cylindrical element 5.2 rotating therein. As shown in Fig. 30, the cylindrical element 5.2 has - in each of the two bases - a female-shaped gripping element 5.3 with dimensions slightly larger than those of the male-shaped gripping elements 1.7, 2.6 of the locking devices 1 , 2. The female-shaped gripping elements 5.3 present in the remaining faces enable the connection of other four male-shaped gripping elements 1 .7, 2.6 of the locking devices 1 , 2. Upon rotating the cylindrical element 5.2, a second removable element can be rotated at any angle with respect to the first removable element. As shown in Fig. 31 , the second cube-shaped angular connector 5 may also have male-shaped gripping elements 5.4 each of which is formed by a pin at whose free end there are fixed two fins. In this case, the gripping elements of the locking devices 1 , 2 are female-shaped.
In another preferred embodiment, shown in Figs. 32, 33, the second locking device 2 is provided with only one male-shaped guide element 2.7 projecting from the support 2.2, inside the central locking element 2.1 . The guide element 2.7 ends up inserted into the end of the first longitudinal guides 1 .4 of the central locking element 1 .1 of the first locking device 1 . Should the latter be solid, it would be provided - at the free end thereof - with a transversally extending channel suitable to house the male-shaped guide element 2.7.
In another preferred embodiment, shown in Figs. 34 - 36, the second locking device 2 is provided with only one female-shaped guide element 2.8 obtained in the support 2.2, inside the central locking element 2.1 . Each female-shaped guide element 2.8 houses an equivalently-shaped male-shaped projection 1 .8 obtained in the free end of the central locking element 1 .1 of the first locking device 1 .
In another preferred embodiment, shown in Fig. 37, the central locking element 1 .1 of the first locking device 1 is hexagonal-prism-shaped with six edges 1 .9 projecting towards the external. Such edges 1 .9 of the first locking device 1 are housed in the grooves obtained in the inner wall of the central locking element 2.2 of the second locking device 2, also hexagonal-prism-shaped. Such edges 1 .9 and grooves form the guide elements having a longitudinal axis parallel to that of the central locking element 1 .1 of the first locking device 1 .
Thus, in these last preferred embodiments, the first guides 1 .4 of the central locking element 1 .1 of the first locking device 1 have only one function: enabling the sliding of the pins 3.2 therein.
The system for assembling removable elements thus conceived is susceptible to further numerous modifications and variants all falling within the inventive concept. In addition, all details can be replaced by other technically equivalent ones.
