Description

STACKABLE HINGE CONNECTION
FIELD OF THE INVENTION
The present invention relates to a hinge connection comprising a male member applied on a base plate and a pair of female members applied on a further base plate, said male member having protrusions provided to be hinged and resiliently fitted between the pair of female members applied on a further base plate. The male member of the hinge connection is being formed by two parallel male legs, wherein each leg comprises protrusions comprising cogs or cut teeth. The female member is formed by two parallel female legs and each of the female members comprises a through hole for engaging said protrusions of the male legs. The present invention further provides construction elements comprising the hinge connection members of the instant application. In a particular embodiment such construction elements are stackable, and allow the construction of complex three-dimensional structures without loss of flexibility.
BACKGROUND TO THE INVENTION
Hinge connections are regularly used for the connection between two or more construction elements, for example as used in building blocks in toys. An example of such a hinge connection is disclosed in WO9830808. Said hinge connection comprises a male member applied on a base plate and a pair of female members applied on a further base plate. The male member is hingedly and resiliently fitted between the female members, wherein the male members comprise protrusions, fitting in a through hole that is present in each female member. Said hinge connection can further form a construction element comprising at least one base plate with at least one male member and at least one further base plate with at least one pair of female members. These construction elements are for example used as building blocks and enable to create complex structures.
Typical for the hinge connection as described in WO9830808 is that the protrusions of the male members are cylindrical and have a smooth surface. The male members of the hinge connection resiliently fit between a pair of female members wherein the smooth cylindrical protrusions fit into a through hole present in each female member. A disadvantage of these smooth surfaces of both the protrusions and the through hole is that the hinge connection is not stable and quite some backlash is present. In particular, the hinge connection allows the construction elements to rotate 180°, but because of the smooth surfaces it does not allow the construction elements to stay in certain fixed positions between 0° and 180°. Under influence of time and/or gravity, constructions elements can start to bend. This is particularly disadvantageous when creating complex structures.
Another disadvantage of the hinge connection as disclosed in WO9830808 is that after fitting of the male member between a pair of female members, the hinge connection is firmly established and can only be disconnected by exerting a considerable amount of power. It is accordingly an object of the present invention to provide an improved and robust hinge connection that can be used in the construction of complex three-dimensional structures without loss of flexibility. To said extend, the present invention further provides stackable construction elements comprising the hinge connection members as detailed hereinafter.
SUMMARY OF THE INVENTION
It is accordingly an object of the present invention to provide a hinge connection (1 ) comprising a male member (2) applied on a base plate (4) and a pair of female members (5) applied on a further base plate (7) wherein said male member has protrusions (8) provided to be hinged and resiliently fitted between a pair of female members (5) applied on said further base plate (7). The male member (2) is formed by two parallel male legs (3), wherein each leg comprises one of said protrusions, wherein said female member (5) is formed by two parallel female legs (6) and wherein each of said female members comprises a through hole (10) for engaging one of said protrusions, wherein the two parallel female legs (6) are connected by an intermediary piece (9) and wherein said through hole (10) extends through said female legs (6) and said intermediary piece (9). Typical for the present invention is that the protrusions (8) on each leg of the male member comprise cogs or cut teeth and that the through hole (10) of the female member (5) comprises cogs or cut teeth to accommodate the cogs or cut teeth of said male protrusions. Further, and also typical for the present invention is that the intermediary piece (9) and/or the female legs (6) of the female members (5) are interrupted, resulting in an increased ease of use without loss of stability of the hinge connection.
In a preferred embodiment of the hinge connection (1 ) according to the invention, the intermediary piece (9) of the female member (5) is mounted offset from the further base plate (7). This enables to further reduce the thickness of the female members and consequently to further reduce the cooling time upon moulding and still ensure the stability of the connection. In a further and still another embodiment of the present invention, the intermediary piece (9) and the female legs (6) of the female member (5) are interrupted in the longitudinal direction (16). In another embodiment, the intermediary piece (9) of the female member (5) is interrupted in the transverse direction (17).

In order to improve the hinge movement of the hinge connection according to the invention, said intermediary pieces (9) are cylindrical pieces. Typical for the present invention is that the protrusions (8) of the male members (2) are protrusions comprising cogs and cut teeth and the through holes (10) of the female members (5) also comprise protrusions (8), in particular cogs or cut teeth to perfectly receive the cogs or cut teeth of said male protrusions (8) of the male members (2).

DETAILED DESCRIPTION OF THE INVENTION
The present invention is directed to a hinge connection and a construction element comprising said hinge connection. In particular, the present invention provides an improved and robust hinge connection that can be used in the construction of complex three-dimensional (3D) structures without loss of flexibility but with maintenance of stability. As shown in Figure 1 , the hinge connection (1 ) according to the present invention comprises a male member (2) applied on a base plate (4) and a pair for female members (5) applied on a further base plate (7), wherein said male member (2) is fitted between a pair of female members (5) formed by two parallel female legs (6) on said further base plate (7). Typical for the present invention is that the male member (2) has protrusions (8) on each leg of the male member (2), wherein said protrusions (8) comprise cogs or cut teeth. These protrusions (8) are provided to have said male member (2) hinged and resiliently fitted between a pair of female members (5). Also typical for the present invention is that each of the female members (5) comprises a through hole (10) wherein said through hole (10) comprises cogs or cut teeth to receive the protrusions (8), in particular the cogs or cut teeth of the male member (5). Further, and also a crucial element of the present invention, is that the two parallel legs (6) are connected by an intermediary piece (9) wherein said through hole (10) extends through said female legs (6) and said intermediary piece (9). Typical for the present invention is that said intermediary piece (9) and/or the female legs (6) of the female member (5) are interrupted. In a particular embodiment, the intermediary piece (9) is interrupted in the transverse direction (17), as shown in Figures 1 and 2. In another particular embodiment, and shown in Figures 2 and 3, the intermediary piece (9) and both the female legs (6) are interrupted in the longitudinal direction (16). In a preferred embodiment and as shown as well in Figures 2 and 3, the intermediary piece (9) is interrupted in both the transverse direction (17) and the longitudinal direction (16) and the female legs (6) are interrupted in the longitudinal direction (16). The interruptions of both the intermediary piece (9) and the female legs (6) are of particular importance for the transfer of forces that are applied when creating the hinge connection (1 ). Even more in particular, since the interruptions (16, 17) are present in both directions, both longitudinal and transversal, the forces that are applied when creating the hinge connection are transferred in both these directions. As a result, the male member (2) is easily fitted between a pair of female members (5) thereby increasing the ease of use, without loss of stability of the hinge connection. The interruption of both the intermediary piece (9) and the female legs (6) thus facilitates the creation of the hinge connection (1 ). Without the presence of said interruptions, the intermediary piece (9) and the female legs (6) would be much more rigid, thereby impeding the positioning of the male member (2) in between the pair of female members (5). With the present invention, the male member (2) can be easily and transiently, though still rigidly, positioned in between said pair of female members (5), and it makes it easier to separate the hinge members when required. As shown in Figure 1 as well, the male (2) and female (5) members are preferably provided with rounded free ends. In another embodiment, the male (3) and female (6) legs comprise rounded borders. As a result of both the rounded free ends and the rounded borders, the hinge movement of the hinge connection is facilitated and the risk for injuries when creating complex structures with the construction elements is avoided. This is of particular importance when the construction elements are used as a toy.
The present invention further discloses a construction element (20) comprising a hinge connection (1 ) as outlined herein above. In one embodiment of the present invention, the construction element (20) comprises at least one base plate (4) with at least one male member (2) as detailed herein above. In another embodiment, the construction element (20) comprises at least one further base plate (7) with at least a pair of female members (5) as detailed herein above. In yet another embodiment, the construction element (20) according to the present invention comprises at least one base plate (4) with at least one male member (2) and at least one further base plate (7) with at least a pair of female members (5).
In particular, the construction element (20) of the present invention comprises at least base plates and/or further base plates forming a closed area. In a preferred embodiment, and as shown in Figures 1 , 2 and 3, the construction element (20) according to the present invention comprises two parallel base plates (4) and two parallel further base plates (7) forming together a square. In said construction element, the two base plates (4) each comprise male legs (3) applied symmetrically with respect to the middle of the base plate (4) and wherein the two further base plates (7) each comprise a pair of female members (5) wherein each female member (5) extends at an extremity of the further base plate (7) in such a manner that one of the female legs (6) of said female member (5) extends in prolongation from an extremity of one of said base plates (4). In yet another embodiment, the construction element (20) comprises 3 base plates (2) each comprising a male member (5) and 3 other base plates without any female or male member.
Referring now to Figures 1 and 2, typical for the hinge connection (1 ) according to the present invention is that it is established via the presence of protrusions (8). Said protrusions are present on each leg (3) of the male members (2) and allow the male member to be hinged and resiliently fitted into the gear protrusions of the female member (5). Typical for the present invention is that said protrusions on each leg of the male member comprise cogs or cut teeth. These cogs or cut teeth perfectly fit into the cogs or cut teeth of the through hole (10) of the female member (5). Because of the presence of said protrusions, in particular comprising cogs or cut teeth, an improved and robust hinge connection between two construction elements is provided that can be used in the construction of complex three-dimensional structures without loss of flexibility. With the hinge connection according to the present invention, the fitting of the cogs or cut teeth of the male protrusions into the cogs or cut teeth of the female member (5) allows adjacent construction elements to be positioned in several different angles relative to each other. In particular, by fixing the relative angle between two construction elements, the 3D structure becomes more rigid, and its shape is at least partially constrained and dependent upon the choice of the fixed relative angle between any two adjacent elements included in the multi-panel structure. In a preferred embodiment, the relative angle between two construction elements according to the present invention is fixed at up to 1 1 discrete angles: 90°, 108°, 126°, 144°, 162°, 180°, 198°, 216°, 234°, 252°, and 270°. The ability to fix the relative angle between each pair of coupled construction elements enables a user to construct 3D structures of significant diversity in both shape and form. With 1 1 possible angle choices between each pair of coupled construction elements, the shape of the possible 3D structures is practically unlimited.
In a particular embodiment of the present invention, and as shown in Figure 4 and 5, the construction element comprising at least one further base plate (7) with at least a pair of female member (5), further comprises two linking members (21 ) applied on a base plate and provided to be resiliently fitted on two female members. Said female members are formed by two parallel female legs and comprise a through hole and wherein the two parallel female legs are connected by an intermediary piece and wherein said through hole extends through said female legs and said intermediary piece. The linking members (21 ) of said construction element are characterized in that they comprise a C-shaped curved leg (22). As a result, the C-shaped curved legs (22) of the linking members (21 ) resiliently fit onto the female members of a second construction element. As evident from Figures 1 , 2 and 3, the construction element according to the present invention comprises a connection plate (1 1 ) that connects the base plates (4) and/or the further base plates (7) and extends in a plane perpendicular to said base plates. Said connection plate (1 1 ) enhances the strength of the construction element and enables to form a container for receiving all kind of objects or goods, for example sweets. The formed container may also be used as packaging. In a preferred embodiment, the connection plate (1 1 ) connects two base plates (4) and two further base plates (7) and extends in a plane perpendicular to said base plates. Typical for the present invention, and as can be observed in Figures 1 and 2, the connection plate (1 1 ) of the construction element (20) comprises a ridge (12) at the connections between the connection plate (1 1 ) and the base plates (4) and further base plates (7). In an even further embodiment, said ridge (12) comprises one or more openings (15); in particular one or more openings at each of the connections between the connection plate (1 1 ) and the base plates (4) and further base plates (7). Even further, and as shown in Figure 3 the base plates (4) and further base plates (7) of said construction element (20) comprise one or more protrusions (18); in particular at the side opposite to the side connected to the connection plate (1 1 ); more in particular at the side opposite to the side connected to the connection plate (1 1 ) and directly opposite to openings (15) at the ridge (12) of the connection plate (1 1 ). The ridge (12) in the connection plate (1 1 ) in combination with the one or more openings (15) and one or more protrusions (18) at the side opposite to the side connected to the connection plate (1 1 ) ensure that multiple construction elements (20) are stackable to each other by clicking the ridge (12) of a first construction element into the base of the three-dimensional structure formed by the combination of the connection plate (1 1 ) with the base plates (4) and/or further base plates (7) of a second construction element, and so on. In a particular embodiment upon stacking of multiple construction elements (20), the protrusions (18) on the base plates (4) and/or further base plates (7) fit in the openings (15) at the ridge (12) of the connection plate (1 1 ).
In a particular and preferred embodiment, and as shown in Figure 1 , the distance between the female legs (6) is equal to L, the distance between the male legs (3) is equal to L, and the height of the legs is equal to L. In a further embodiment, the length of the base plate (4) and the further base plate (7) is equal to 3L and the height of the base plate (4) and the further base plate (7) is equal to L.
The hinge connection and connection elements of the present invention are advantageously made from a material that allows repeated deflections to occur, without permanent deformation thereof. Thickness of the connection elements is chosen so as to obtain similar results. Or expressed differently, the hinge connection as detailed herein above and the construction element comprising said hinge connection are produced in a robust but still flexible material.
