Abstract
Abstract The invention provides a set of building elements for assembling building models to a reduced scale in which the main load bearing areas such as the floor and ceiling surfaces are built up from elements which are positively locked together. This is achieved by providing the elements of plate-like form with grooves extending around their edges which have an increased internal cross-section into which complementary tongue fillets are inserted. An important feature of this invention provides anchoring elements which can be connected to the upper edges of the wall elements and positively connected together to form a stabilising frame for the top of the said wall elements.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
394 words
In a model building erected from a set of building elements, a combination comprising a plurality of floor plates of rightangular outline each having a bottom portion circumferentially bounded by first edge surfaces, and a top portion having a top surface and circumferentially bounded by second edge surfaces parallel to and offset with respect to said first edge surfaces in direction toward the center of said top surface, each of said floor plates being formed with a peripheral L-shaped groove along each side, each of said grooves having one leg which opens on the respective first edge surface and another leg which extends upwardly toward said top surface of said floor plate inwardly of said first and second edge surfaces, said floor plates of said plurality being arranged adjacent one another with the associated first surfaces of any associated two of said floor plates juxtaposed with one another and with the legs which open on said associated first edge surfaces facing one another so that the respective L-shaped grooves together form a U-shaped channel, said bottom portions and said second edge surfaces of said associated floor plates simultaneously defining an upwardly open channel of a predetermined width at said top surfaces between said associated floor plates; a plurality of tongue fillets of Ushaped configuration inserted into the respective U-shaped channels of said associated floor plates and interconnecting the same to form a floor of a selectable configuration and circumferentially bounded by the marginal ones of said floor plates; a plurality of elongated marginal fillets each formed with an L-shaped projection inserted into the respective L-shaped grooves of said marginal floor plates and interconnecting the same in the circumferential direction of said floor and with an upstanding strip-shaped projection extending along the juxtaposed second edge surfaces of the respective marginal floor plates to form therewith an additional upwardly open channel of said predetermined width; and a plurality of wall elements having spaced parallel top and bottom edge surfaces, at least said bottom edge surface of each wall element being provided with at least one tongue projecting therefrom and having a width substantially corresponding to said predetermined width of said upwardly open channel, said tongues of at least certain of said wall elements being received in said additional upwardly open channels so that said certain wall elements form a center peripheral wall of said model building.
Claim 2
Dependent Claim

In a model building erected from a set of building elements, a combination comprising a plurality of floor plates of rightangular outline each having a bottom portion circumferentially bounded by first edge surfaces, and a top portion having a top surface and circumferentially bounded by second edge surfaces parallel to and offset with respect to said first edge surfaces in direction toward the center of said top surface, each of said floor plates being formed with a peripheral L-shaped groove along each side, each of said grooves having one leg which opens on the respective first edge surface and another leg which extends upwardly toward said top surface of said floor plate inwardly of said first and second edge surfaces, said floor plates of said plurality being arranged adjacent one another with the associated first surfaces of any associated two of said floor plates juxtaposed with one another and with the legs which open on said associated first edge surfaces facing one another so that the respective L-shaped grooves together form a U-shaped channel, said bottom portions and said second edge surfaces of said associated floor plates simultaneously defining an upwardly open channel of a predetermined width at said top surfaces between said associated floor plates; a plurality of tongue fillets of Ushaped configuration inserted into the respective U-shaped channels of said associated floor plates and interconnecting the same to form a floor of a selectable configuration and circumferentially bounded by the marginal ones of said floor plates; a plurality of elongated marginal fillets each formed with an L-shaped projection inserted into the respective L-shaped grooves of said marginal floor plates and interconnecting the same in the circumferential direction of said floor and with an upstanding strip-shaped projection extending along the juxtaposed second edge surfaces of the respective marginal floor plates to form therewith an additional upwardly open channel of said predetermined width; and a plurality of wall elements having spaced parallel top and bottom edge surfaces, at least said bottom edge surface of each wall element being provided with at least one tongue projecting therefrom and having a width substantially corresponding to said predetermined width of said upwardly open channel, said tongues of at least certain of said wall elements being received in said additional upwardly open channels so that said certain wall elements form a center peripheral wall of said model building.
Claim 3
Dependent Claim
55 words
A set as defined in claim 1, and further comprising a parapet element for engaging a respective marginal fillet of said plurality of interconnected floor plates forming a flat roof, said marginal fillet defining at least a part of a marginal channel and said parapet element having at least one projection engaging said marginal channel.
Claim 4
Dependent Claim
70 words
A set as defined in claim 1, wherein said top edge surface of the respective wall element is provided with at least one additional tongue similar to said longitudinal tongue and projecting from said top edge surface; and further comprising a plurality of top anchoring elements each provided with at least one anchoring groove having a width substantially corresponding to the width of said additional tongue for engaging the same.
Claim 5
Dependent Claim
60 words
A set as defined in claim 3, and further comprising at least one wall crown element provided with a crown groove similar to said anchoring groove for engaging the respective additional tongue and having a crown projection similar to sAid longitudinal tongue for engaging the respective anchoring groove, whereby the upright dimension of a respective wall element may be extended.
Claim 6
Dependent Claim
49 words
A set as defined in claim 3, wherein each top anchoring element has at least two end portions; and wherein each of said end portions is provided with a dovetail-type connector for cooperation with a complementary dovetail connector of an adjacent end portion of an associated top anchoring element.
Claim 7
Dependent Claim
67 words
A set as defined in claim 3, wherein at least one of said wall elements is a door element comprising a frame provided with a hole, a threshold, and a door having two spaced and axially aligned pegs on the upper and lower edge surfaces of said door and engaging said hole and said threshold for pivoting said door about said axis with respect to said frame.
