Description

    INTRODUCTION
  • This invention relates to an element for constructing a structure and particularly, but not exclusively, a toy or model structure. [0001]
  • GB 1378942 discloses planar elements for constructing toy or model structures. These elements are polygonal figures and are typically moulded from plastics material. In use, a plurality of the elements are connected in edge-to-edge fashion to form geometric structures. [0002]
  • The fundamental problem with these elements is that curved surfaces are not provided for and arcuate structures cannot be assembled. [0003]
  • The present invention seeks to overcome these problems. [0004]
    • SUMMARY OF THE INVENTION
  • According to a first aspect of the invention there is provided an element for constructing a structure by detachably connecting a plurality of the elements in edge-to- edge relationship, the element comprising a plurality of margins, at least one of the margins being an arcuate margin, each margin being shaped so as to be releasably connectible to a margin of another element. [0005]
  • A preferred feature of the first aspect of the invention is set out in claim [0006] 2.
  • According to a second aspect of the invention, there is provided an element for constructing a structure by detachably connecting a plurality of the elements in edge-to-edge relationship, the element comprising a plurality of margins, at least one of the margins being an arcuate margin, each margin comprising at least two projections having a recess therebetween, an end-face of one projection being formed with a recessed hinge-socket and an end-face of the other or another projection being formed with a protruding hinge-pip, the arcuate margin being adapted to mate with a complementary margin of another element with the hinge-pip of each element urged into the hinge socket of the other element. [0007]
  • This is advantageous in that two- and three-dimensional curved surfaces and structures can be formed. [0008]
  • Other preferable and/or more preferable features are set out in claims [0009] 4 to 14.
  • According to a third aspect of the invention, there is provided an element in accordance with the first aspect of the invention in combination with a polygonal element, at least one of the plurality of margins of the element being a linear margin, said linear margin being hingedly and detachably connectable in edge-to-edge relationship with a complementary linear margin of the polygonal element. [0010]
  • This advantageously allows structures incorporating strictly polygonal elements, curved and/or partially curved planar elements, and non-planar elements to be constructed. [0011]
  • Preferably, the polygonal element is a planar figure. [0012]
  • The invention will now be more particularly described, by way of example, with reference to the accompanying drawings. [0013]

    • DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Referring to the drawings, an [0021] element 10, typically moulded from plastics material, is shown therein. The element 10 comprises a plurality of margins 12. At least one of the margins 12 is an arcuate margin 12′, and another one of the margins 12 may be a linear margin 12″.
  • In the examples shown, the [0022] margins 12 of the element 10 serve to define a frame or skeletal figure. However, the element 10 may have a solid, or substantially solid, figure.
  • Each of the [0023] margins 12 comprises a projection 14 and a recess 16. In addition, each margin 12 further comprises another projection 18 and another recess 20, formed substantially at opposite ends of the margin 12. The end faces 14 a and 14 b of projection 14, and end face 18 a of projection 18 are parallel or substantially parallel to each other.
  • A hinge-[0024] pip 22, typically in the form of a part-spherical projection, is integrally formed on the end face 14 a of the projection 14, and a complementary hinge-socket 24, typically in the form of a part-spherical recess, is formed in the end face 18 a of the other projection 18.
  • Of course, the positioning of the hinge-[0025] pip 22 and the hinge-socket 24 on the projections 14 and 18 is not limited to the above-mentioned formation. The hinge-pip 22 and the hinge-socket 24 may be interchanged, and the hinge-pip 22 and hinge-socket 24 may be formed facing each other across the recess 16.
  • Each [0026] margin 12 further comprises urging means, typically in the form of a resiliently flexible tongue 14 c, formed by a slot 14 d dividing the projection 14. Each tongue 14 c has an abutment face 15, which corresponds to the end face 14 b of the projection 14. The degree of resilience of the tongue 14 c may be varied by varying its dimensions.
  • Obviously, in a modification, the urging means may be associated with the [0027] projection 18 instead of the projection 14.
  • FIGS. [0028] 1 to 4 of the drawings, show a first embodiment of the element 10. In the first embodiment of the invention, the margins 12 serve to define a substantially two-dimensional planar figure. The element 10 may, for example, take the form of a sector, as shown in FIG. 1, or, in a modification, a generally asymptotic form as shown in FIG. 4, but is not limited to these forms.
  • Referring to FIGS. 5 and 6, a second embodiment of the [0029] element 10 is shown therein. In the second embodiment of the invention, the margins 12 serve to define a three-dimensional non-planar figure. In this case, each arcuate margin 12′ lies or substantially lies in a plane which is different from a plane or planes in which the other margins 12 lie, and each plane intersects at least one of the other planes at an angle, which may or may not be a right-angle.
  • FIG. 5 shows the [0030] element 10 having a part-cylindrical figure, and, in a modification, FIG. 6 shows the element 10 having a part-spherical figure. However, the second embodiment of the element 10 is not limited to these figures, and may have, amongst others, a part-conical figure or a part-frusto-conical figure.
  • FIG. 7 shows [0031] elements 10 having solid figures in use formed into a part-domed structure. Due to the end faces 14 a, 14 b and 18 a of the projections 14 and 18 of the arcuate margins 12′ being parallel, interconnection can be easily effected between two different non-planar elements, and between non-planar elements and planar elements. As shown in FIG. 7, for example, a part-spherical element 10 can be detachably connected in edge-to-edge relationship with another part-spherical element 10 along one of its complementary arcuate margins 12′, and with a part-cylindrical element 10 along another one of its complementary arcuate margins 12′; the part-cylindrical element 10 can be interconnected with the part-spherical element 10 along one of its arcuate margins 12′, with a planar element 10 along another one of its arcuate margins 12′, and with another part-cylindrical element 10 along one of its linear margins 12″, while leaving its other linear margin 12″ available for interconnection with a linear margin 12″ of either a further planar or non-planar element.
  • During the course of such engagement, the [0032] projections 14 and 18 of the arcuate margins 12′ are engaged with the recesses 16 and 20, respectively, of the complementary arcuate margins 12′. The projections 14 and 18 of the linear margins 12″ are engaged with the recesses 16 and 20, respectively, of the complementary linear margins 12″. Due to the parallel end faces 14 a, 14 b and 18 a, arcuate margins 12′ of a planar element 10 and a non-planar element 10, or linear margins 12″ of two elements 10, to be interconnected can be perpendicularly, or substantially perpendicularly, brought into engagement; and arcuate margins 12′ of two non-planar elements 10, or linear margins 12″ of two elements 10, to be interconnected can be colinearly, or substantially colinearly, brought into engagement.
  • The hinge-[0033] pip 22 of each in use margin 12 of each element 10 is located in the corresponding hinge-socket 24 of the margin 12 of the other element, and the corresponding abutment faces 14 d of each element are aligned and resiliently abut each other due to the urging means of the element 10 forcing retention of the hinge-pip 22 in the hinge-socket 24. An assembled condition of the elements is thus maintainable.
  • In this way, structures comprising planar elements and non-planar elements can be assembled. Also, elements with figures defined only by linear margins, such as polygonal elements, complementary to the [0034] linear margins 12″ of the present invention may be advantageously incorporated in structures which include elements with figures defined by at least one arcuate margin 12′ and one linear margin 12″.
  • The embodiments described above are given by way of example only, and various modifications will be apparent to persons skilled in the art. [0035]
