Description

Connection element for a building system Field of the invention
The present invention relates to a connection element comprising a main connector axis (X) and a first end part and a second end part spaced-apart from the first end part along the main connector axis, the first end part and the second end part being connected by an intermediate part. The invention also relates to an assembly of the connection element and a structural element.
Background of the invention
In general, connection elements of the above mentioned type are known in the art.
In EP1068886, a modular toy construction is shown, wherein a connection element comprises a cylindrical intermediate body with intermediate spherical sections limited by transverse notches and opposing beads with a recess. The connecting device interacts with a ring comprising radial U-shaped connectors. The U-shaped connectors comprise a pair of straight members and an inner cylindrical section which is of a greater radius than the straight members. The opposing beads of the connecting device are made to be inserted into the U-shaped connectors by urging the opposing beads against the straight members until the opposing beads are interlocked in the inner cylindrical section, with the possibility of having the connecting device rotating or articulating or detaching in any position. The connecting device can also be connected to different parts of the modular toy constructions such as bars or radial connection members following the same principle of urging the opposing beads of the connecting device against the straight members of the bars or other connector elements, as to create the modular toy construction.
The known connection element has a disadvantage that the connection possibilities are limited to have a building component that can be securely connected to the connecting device via the engagement of its end bead parts. Moreover, by introducing the end bead parts into the U-shaped connectors of the different connector elements, the operating state of the U-shaped connectors is compromised due to the fact that in order to have a strong and flexible connection, the outer diameter of the beads needs to be slightly larger than the entrance area of the U-shaped connectors. This may result in a breakage of the connector by the bending moments created in the U-shaped connectors, such that the U-shaped connectors will break or wear-off after a few connections and disconnections have been performed.
Moreover, the prior art connection elements are limited to a one type of connection in order to built up the desired modular toy construction.
It is therefore an object of the present invention to at least overcome one of the above mentioned disadvantages of the prior art. It is also an object of the present invention to provide a connection element for adjustably or detachably inter-connecting components in different positions in a (toy) building set that makes the connection of the building set parts easier, while its integrity is not comprised by the number of times that the connection element is used. It is a further aim to provide a connection element that provides multiple connection possibilities for assembling different building sets. It is moreover an object of the invention to provide a connection element with which the connection of different components becomes intuitive and does not need any expertise for connecting different components of the building set.

Detailed description of the invention
Fig. 1 shows a side view of the connection element 1 according to the present invention. The connection element 1 as here illustrated comprises a first and a second end part 2, 3 being interconnected via an intermediate part 4, while the first and a second end parts 2, 3 as here illustrated are identical. The first and a second end parts 2, 3 comprise a pair of clamping members 5, 5’ having a clamping groove 6 with a width corresponding to a distance E between the members 5, 5’which is about 2 times the distance F of the outer surface of a first delimitation body 12 from retaining region 10. It should be noted that each of the clamping members 5, 5’ comprises a raised shoulder adjacent the outer end thereof and also preferably comprises an outer tapered portion to ease insertion of the clamping members 5, 5’ into an opening 23 of a structural element as best seen in figure 2.
As shown, the connection element 1 further comprises a clamping grove 6, having a clamping surface 7 comprising teeth 8. The shape of the teeth 8 as here illustrated is a wavy shape, but it can have may shape variations, but they all have the same clamping members 5, 5’. These clamping members 5, 5’ have several basic functions which will be described in more detail below. The distance E as illustrated, corresponds to the distance between the outermost part or retaining surface of each of the opposing teeth 8.
As it can be appreciated, each of the first and second end parts 2, 3 comprises a retainer region 10 being delimited by the first delimitation body 12 and a second delimitation body 13, which is part of the intermediate part 4.
Figure 2 shows one of the first and the second end parts 2, 3 being directed towards a structural element 9. The structural element 9 as illustrated comprises an opening 23 having an inner circumference 24 with a width that is at least equal to the retainer region 10 of the connection element 1. By introducing one of the end parts 2, 3 into the opening 23, it can be chosen to either tight or loose have a click connection. By doing this, the connection element 1 and the structural element 9 can rotate with respect to each other having more or less friction depending on the type of connection established. By clicking the clamping members 5, 5’ into the opening 23, a double function is provided, a temporary connection and it provides an axle wherein an object can rotate. It should be noted that the length of the retainer region 10 can determine the maximum extend of the structural element 9 and/or the width of the opening 23.
Figure 3 shows the one of the first and the second end parts 2, 3 as being directed towards a structural element 9 in a form of a sheet-like material of about 0.3 mm of plastic material e.g. polypropylene before being introduced and clamped into the clamping members 5, 5’. The wavy shape of the teeth 8 allows clamping the structural element 9 and clicking the clamping members 5, 5’ into an opening, as also illustrated in figure 4, wherein the clamping members 5, 5’ can be introduced into the opening 23 of a flexible tube 9, and having the clamping members 5, 5’ being secured by fitting of the raised shoulder portion with a raised rim shaped part of the tube 9.
Figure 5 shows a similar connection as the one shown in figure 2, wherein the connection is effected by tight fitting of the intermediate part 4 of the connection element 1 with the opening 23 of the structural element 9. In order to achieve this type of connection, the outer circumferential diameter of the intermediate part 4 fits tightly into the specific opening 23, having the opening 23 an inner diameter slightly larger than the outer diameter of the intermediate part 4.
As illustrated in figure 6, the connection element 1 can be assembled with a connection bead 18 to create an assembly suitable to connect to different parts having a different thickness. The connection bead 8 comprises a connection part 19 in which the clamping members 5, 5’ can be clamped by clicking the clamping members 5, 5’ into an opening 23 of the connection bead 18. The connection bead 18 comprises a clamping part 20 having clamping surfaces 20’ that are at a bigger distance from each other than the clamping surfaces 7 of the clamping members 5, 5’. The connection bead 18 can be rotated around the main connection axis X of the connection element 1 when assembled with the connection element 1 having little friction due to the fact that the inner circumference diameter 24 of the opening 23 is slightly bigger than the outer circumferential diameter of the retainer region 10.
It should be noted that the connection bead 18 can be made of any suitable material; preferably the material of the connection bead 18 will be the same as the material of the connection element 1.
Figure 7 shows the connection bead 18 having the clamping part or groove 20, 20’ slightly bigger than the thickness of the structural element 9. The structural element 9 as here illustrated is in a form of a sheet like material providing some friction when the structural element 9 is slide in or inserted into the clamping groove of the connection bead 18.
Figure 8 shows the connection element 1 according to a further embodiment of the present invention, wherein the second end part 3 comprises clamping members 5, 5’ and a clamping groove 6. This provides the possibility to connect the first end part 2 to the connection bead 18 as the one illustrated in figure 7 in order to allow multiple different connections. Moreover, the illustrated configuration of the connection element, allows two different types of connections with structural elements in the form of a sheet-like material that comprise different thicknesses.
Figures 9 and 10 show another embodiment of the present invention wherein two connection elements 1, Γ are shown having two different second end parts 3 that can be interconnected to each other in order to create a hinge connection. The first connection element 1 comprises a second end part 3 comprising a pair of clamping members 5, 5’ defining a clamping groove 6 there between and a pair of projections 16, 16’ projecting towards each other. The second connection element Γ comprises a ring-shaped end 15 that can be clamped into the clamping members 5, 5’ of the first connection element 1 and be securely retained by insertion of the pair of projections 16, 16’ between to the opening of the ring shaped end 15, when clamped. It should be noted that the projections 16, 16’ in combination with the ring shaped end 15 act as bearings for the hinge connection. Moreover, the thickness of the ring 15 can be a fraction longer than width of the clamping groove 6, to provide the hinge with some friction when moving. It should be noted that the ring shaped end 15 can be also inserted into the first end part 2 of the first connection element 1 (not illustrated).
Figure 11 shows the connection element 1 having the same hinge function as describe above, wherein instead of being connected to the a second connection element Γ it is connected to a structural element 9. The structural element 9 comprises a connecting part 25 which can be clamped into the clamping members 6 of the connection element 1 and securely retained by insertion of the pair of projections 16 into the opening 23 of the structural element 9. As a result, a hinged structural element 9 is obtained. The thickness of the structural element 9 can be a fraction bigger than the clamping groove 6, as to provide the hinge with some friction when moving.
As shown in Figures 12 and 13, the connecting element 1 comprises an intermediate part 4 having two bent parts 17, 17’, the first and second end parts 2, 3 have a pair of clamping members 5, 5’, with a clamping groove 6 defined by opposing flat clamping surfaces 7, 7’. A connection bead 18 having a substantially round shape is also shown. The connection bead 18 comprises a connection part 19 being comprising a hollow longitudinal shaped connection that can fit into the clamping members 5, 5’. As illustrated, the connection part 19 is defined by parallel walls having curved ends. This enables the assembly to have a movement of about 90°. The intermediate part 4 of the connection element 1 comprises a straight part located in between the two bent parts 17 allowing the structural part 9, as best seen in figure 13, to have a limited movement of the structural element 9 between the bent parts 17. In this manner, the free movement of the structural element 9 along the main connection axis X is restricted, in case the opening 23 of the structural element 9 being bigger than the outer diameter of intermediate part 4. As illustrated in figure 12, the assembly of the connecting element 1, the connection bead 18 and the structural element 9 provide many possible combinations of all the parts and functions as mentioned above.
Figures 14a-14d show several embodiments of end parts of connection element 1 having a clamping groove 6 formed in between the opposed clamping members 5, 5’.
As illustrated, the clamping members 5, 5’ have clamping surfaces 7, 7’ comprising flat surfaces, wavy surfaces defining curved teeth 8, straight angled teeth 8 or teeth 8 having a sharp ends. It should be noted that the distance E between the teeth 8 and the clamping surface 7 in each clamping groove 6 should be about the same distance in each possible configuration.
It should be noted that, the distance E as illustrated in each of the end parts of connection element 1 should be defined by the outermost teeth part of the teeth 8 and the clamping surface 7.
In Figure 15 a view of the connection element 1 wherein the intermediate part 4 has a bent 17 of about 90° is shown. The first end part 2 of the connection element 1 is being connected by insertion of the clamping members 5, 5’ into the opening 23 of the structural element 9. The second end part 3 has been assembled with a connection bead 18. The connection bead 18 which comprises the clamping groove 20, 20’, as shown in drawing figures 6 and 7, slightly bigger than the thickness of the structural element 9’, being the structural element 9’ clamped into the clamping groove 20, 20’ of the connection bead 18 by insertion of the structural element 9’into the clamping groove 20, 20’. By having this type of assembly, the structural element 9’ can be rotated 360° by simply adjusting its position manually, as to achieve a desired angle or position.
Figure 16 illustrates an embodiment wherein the connection element 1 comprises a third transverse connector element 30 in a form of a third end part. As illustrated, each of the end parts 2, 3, 30 of the connection element 1 are spaced apart from each other, at an angle a of about 120°. These end parts are embodied as substantially transverse connectors 21, 22 for fastening different structural elements 9 together. As shown in figure 15, the second end part 3 of the connection element 1 has been assembled with a connection bead 18 and the connection element 9’ clamped into the clamping groove of the connection bead 18. The first and third end parts 2, 30 comprise the clamping groove 6, having the clamping surface 7 provided with teeth 8 into which a sheet-like element 9 has been clamped into an assembled state.
It should be noted that the angle a between each of the end parts 2, 3, 30 or between the substantially transverse connectors 21, 22, should not be limited to the illustrated embodiment. The angle a can be determined by the type of connection and/or structure to be built, thus not limited to the embodied connection element 1.
Figures 17 and 18 show different view of a toy construction i.e. a toy butterfly, embodying the connection element 1 and the assemblies of the invention. As it can be appreciated, the toy butterfly 40 incorporates a number of different connection elements 1 according to the invention in all its connection points. As best shown in figure 17, the antennas of the toy butterfly 40 comprise the connection element 1 being in assembled state with a sheet-like shape structural element 9 which has been clamped into the clamping groove 6 of the end part 2, 3 and retained by the teeth 8. Moreover, as illustrated, the different connections that form the toy butterfly 40 have been made by using the connection elements 1 as described above.
As best seen in figure 18, the legs of the toy butterfly 40 comprise the hinge connection as shown in figure 11, wherein the first end part 2 of the connection element 1 has been assembled with a connection bead 18 as to add the possibility to clamp another structural element 9 (not illustrated) in-between the clamping surface 20, 20’ of said connection bead 18.
Figures 19 and 20 illustrate a further embodiment of the invention wherein the connection element 1 as shown, has the same configuration the connection element 1 of figure 9. In the embodied connection element 1, the first end part 2 of the can be connected to a connection bead 18’ as to create an assembly suitable to connect to different structural elements 9 (not illustrated). The connection bead 18’ comprises a connection part 19 in a form of a clamp, in which the clamping members of the first end part 2 can be inserted into an opening 23 of the connection bead 18’ as to securely connect the connection bead 18’ to the connection element 1. The connection bead 18’ further comprises clamping elements 30 comprising opposing clamping surfaces 29 in the internal part of each of the clamping elements 30. The clamping elements 30 are connected to the connection part 19 by means of a pair of connection arms 27. Moreover, each of the opposing clamping surfaces 29 comprises a pair of outstanding elements 28 in a form of projections, projecting towards each other. In use, the clamping elements 30 can be clamped into the opening 23 of the structural element 9 (not illustrated). The connection arms 27 assist the clamping elements 30 when the clamping elements 30 are clamped into opening 23 of the structural element 9, as by being biased towards each other in a simple manner. In this way, the projections 28 will be securely retained when inserted into the opening 23 of the structural element 9, resulting in a hinged connection between the connection bead 18’ and the structural element 9. It should be noted that the connecting elements 28 act as bearings for the hinge connection.
It should also be understood that the skilled person will recognize that the connection element and the different assemblies here illustrated could also be used in different toy constructions that the one illustrated.
