Sets of building elements of this kind are referred to hereinafter as being of the kind specified and serve as planning building kits for architects for making up models of buildings to thereby facilitate the spatial representation in the course of planning operations; they are also used for demonstration on buildings and at ex hibitions. Furthermore, they find application in model railway installations and the like.
In known sets of building elements a serious disadvantage is that unintentional detachment of the individual building elements cannot be avoided, particularly in the case of the floor plates, which have to bear the entire weight of the remainder of the parts of the building model, when it is being handled.
An object of the invention is to provide a set of building elements of the kind specified in which the floor elemcnts cannot inadvertently become detached.
Thus, in accordance with the invention, in a set of building elements of the kind specified the floor elements are plate-like, the edges of which define grooves, the walls of each groove define an internal portion of the groove of increased cross-section, and tongue fillets are provided having a pair of correspondingly shaped limbs for positively connecting adjacent floor elements so as to form a floor plate.
By reason of the positive connection of the floor elements by means of the shaped tongue. fillets to define flooror ceiling surfaces, any unintentional detachment of individual floorelements is rendered impossible, appreciable stability and rigidity being obtained at the same time. It is precisely these characteristics which are essential requirements for building models, since their dimensional and other stability is determined almost entirely by the floorand, if desired, the ceiling surfaces.
According to a feature of the invention the set of building elements includes elongated anchoring elements which are positively interconnectible at their ends and which have longitudinal grooves in one face thereof for receiving tongues provided in the upper edges of the wall elements, the anchoring elements thereby providing, when assembled, an anchoring frame for the upper edges of the wall elements.
Such a feature provides the advantage that the wall elements can be connected to form aligned units of stable shape, which, if desired, can support a further storey or a roof and which, if desired, may be lifted off for the purpose of more detailed explanation.
The invention also provides for only a small number of types of building elements, which moreover are easy to manufacture whilst providing a large range of sizes of the model.
Conveniently. the set may include marginal fillets for forming a margin around a floor plate, said marginal fillets having a single shaped limb for positive connection with respective adjacent floor elements.
In one preferred form of the invention edges of the floor elements define a groove of re-entrant L-shape and the tongue fillets are of U-shaped cross-section.
According to a further feature of the invention wall elements are provided with further tongues along their lower edges and the margins of the upper portion of each floor element are rabbe'ted relative to the margins of its lower portion in plan view by half the thickness of said further tongues of the wall elements, the floor elements, when assembled, thereby providing a grid of grooves with a width equal to the thicknessof said further tongues.
Thus, it will be appreciated that to build a model the elements are inserted by means of the tongue at their lower end into the groove grid of the floor plate; and anchoring elements are assembled on individual wall elements corresponding to the perimeter of the floor plate and the internal walls of the model, a positive interconnection between the anchoring elements being provided by a plugged connection, e.g., dovetail joints.
Thanks to the anchoring frame thereby provided, it is not necessary to interconnect the wall elements at their vertical adjacent ends, which considerably simplifies assembly of the model.
In this way it is possible to build up individual storeys of a multi-storey building model and also roofs in the form of units which are accurately to scale, and thanks to their stability, to dismantle them without attachment of individual building elements and also to swap them around.
The building elements may consist of two dishshaped interengaging parts. By reason of this two-part construction, the elements can, in simple manner, be injection moulded in plastics, without the need for the grooves to be'cut in the plate-shaped blocks; the two parts may then be interconnected by ultrasonic welding.
A wall element in the form of a door may be assembled as a unit from individual parts, from a frame consisting of two essentially like halves, advantageously joined by ultrasonic welding, and which has two lower tongues for insertion into a groove of the grid, as well as one upper tongue, for engagement in the groove of an anchoring element, as well as a door threshold with a step insertable in the grid groove between the lower tongues and a panel with plugs extending therefrom, one of which is accommodated in a bore of the frame and the other of which abuts against the step of the door threshold. By these means, on the one hand, the individual parts of the door can be produced in a rational manner and, on the other hand, a very simple construction of the door results. Advantageously the two identical halves of the frame can be provided with extensions and bores which facilitate centering and for many applications provide a connection of adequate strength, so that if desired any additional ultrasonic welding can be dispensed with.
In order to increase the number of possible variations of the models, the building set, in accordance with the invention, may have wall elements which have a groove at their lower end and a tongue at their upper end. Depending on the number of wall elements arranged one above the other, different heights of storeys result. In this arrangement the groove of the lowest element accommodates the tongue of a wall element; the tongue of the topmost element engages a groove on the underside of an anchoring element.
In order that the invention may be readily understood, characteristics and advantages thereof will be explained in greater detail, by way of example, with reference to embodiments in the drawings, in which:
FIG. 1 shows an exploded view of a storey of a building model, whose floor surface consists of quadrilateral floor elements;
FIG. 2a is a perspective representation of a two-part floor element according to FIG. 1;
FIG. 2b shows the joint between floor elements by means of U-shaped tongue fillets in perspective representation;
FIG. 2c shows an enlarged section on the line AA in FIG. 2b;
FIGS. 3a-d show an elevation of the sides facing each other of a two-part floor element according to FIG. 2 as well as sections through these parts;
FIG. 4 shows a marginal fillet;
FIG. 5 shows a further embodiment of marginal fillets;
FIG. 6 shows the arrangement and construction of the wall elements;
FIG. 7 shows an embodiment of a building element for doors;
FIG. 8 shows an embodiment of anchoring elements;
FIG. 9 shows a further embodiment of an anchoring element as well as a part of an anchoring frame mounted on the wall elements;
FIG. 10 shows an embodiment of a superimposable wall element;
FIG. 11 shows an embodiment of a parapet fillet for fiat roofs.
In accordance with FIG. 1, the floor surface of the storey consists of floor elements 1, which are positively connected by tongue fillets 2 and which are bounded at their margins by marginal fillets 3. The groove grid which is formed when these elements are connected receives the wall elements, of which a solid wall element 4 and a window element 7 are shown. The anchoring frame consists of individual anchoring elements, some of which are designated 6, 8, 10, 11, which are shown in greater detail in FIGS. 8 and 9, and which will be explained later. The anchoring frame is mounted on the upper tongues of the wall elements. A further storey can be built up as described hereinbefore and mounted on the anchoring frame. A second plate corresponding to the floor surface may also be laid on the anchoring frame, which, for example, then defines the flat roof of a bungalow. For this purpose some of the anchoring elements have tongues on their upper sides, which engage the grooves on the underside of the marginal fillets. Such an anchoring element is referenced 5 in FIG. 1 and the tongue is referenced 5'.
In accordance with FIGS, 2a-c each floor element has at each of its edges a longitudinally extending, reentrant L-shaped groove 12, the horizontal or leg section thereby opening from the respective edge and the inner end of the groove being effectively of increased cross-section. The upwardly directed or upright section terminates approximately at the level at which the upper portion 14 of the floor element is rabbcttcd; the rabbets are provided around the edge of the upper portion of the floor element and are half the thickness of tongues provided on the wall elements (FIG. 21'). By reason of their rabbcttcd upper portions, when assembled, adjacent floor elements form a grid of grooves which intersect at right-angles and whose width is equal to the thickness of tongues provided on the wall elements.
In accordance with FIGS. 3a-d, each floor element consists of two dished parts, one part providing a stepped wall 16 extending from the lower portion 13, the upper edge of which fits within an inner wall of a double-wall section 17 extending from the upper portion 14. The lower edge of said inner wall engages the step of wall 130. Thus the upright of the L-shaped groove is provided by the space between the double wall section 17, whilst the leg section is provided by the spacing of the lower and upper portions 13, 14 respectively. This two-part configuration rationalises the manufacture in plastics, without the need for producing grooves by a cutting operation. It will be appreciated that the upper and lower portions can be in the form of like dished parts, which are welded together at their ends with the L-shaped grooves formed therein.
The adjacent floor elements are interconnected by means of complementary U-shaped tongue fillets 2 (FIGS. 1 and 2), whilst marginal fillets 3 (FIGS. 1, 2c, 5) are arranged along the margins of the floorand ceiling surfaces. Referring to FIG. 4, the marginal fillets have L-shaped tongues 21 and are rabbcttcd at the level of the top of the upright section of the L-shaped tongues by half the tongue thickness of the wall elements. The rabbcttcd sections of the marginal fillets cooperate with the rabbets of adjacent outer floor elements to define a marginal groove. As shown in FIG. 4, the tongues do not extend over the entire length of a marginal fillet, so that the marginal fillets which abut each other at right-angles at a corner of the floor plate can be arranged flush one above the other. As shown in FIG. 5, the length of the marginal fillets advantageously corresponds to a multiple of the elementary grid length. Regions of weakness Zl enable subdivision of an element, in order to achieve corner connections with a flush finish.
As shown in FIG. 5, the undersides of the marginal fillets have continuous grooves 22 and these grooves receive the tongues 5' of the anchoring elements 5.
In FIG. 6 a plurality of wall elements are shown in plan view inserted into the grooves which intersect at right-angles, i.e., the groove grid. The width of the wall elements 4 (FIG. 1) is equal to the distance between the centre lines 23 of two adjacent grooves in FIG. 6, i.e., also equal to the elementary grid length of the floor elements. The width of the wall element 25 for an interior wall is equal to the distance between the centre lines 24 of two adjacent grooves, reduced by half the wall thickness of the wall elements 4. correspondingly the width of the adjacent wall element 26 may be equal to the distance between two centre lines 24, so that in the case of a square groove grid as in FIG. 6 the length of wall element 26 is identical to that of elements 4, whilst the abutting wall element 27 has a recess whose depth is equal to half the wall thickness and whose width is equal to the full wall thickness. By means of wall elements, whose width is equal to half the grid 7 length, it is possible to transpose window elements and the like.
All the wall elements have at their upper and lower ends tongues of substantially the same cross-section. The upper tongues referenced 28 in FIGS. 1 and 6 engage with the grooves formed in the undersides of the anchoring elements, whilst the lower tongues (not shown in FIGS. 1 and 6) are received by the groove grid. The wall elements shown consist of two ultrasonically welded together halves. In the same way as the floor elements, they may consist of two dish-shaped inter-engaging portions.
FIG. 7 shows a door element 29 in accordance with the invention, which consists of a door frame 30, a door panel 31 and a door threshold 32. The door frame consists of two identical halves, which are also ultrasonically welded together. This is indicated by the welding seam 40. The upper peg 33 of the door panel protrudes into a bore (not shown) in the frame, whilst the lowerpeg 34 is received by a channel formed by a shoulder 35 of the door threshold 32 inserted into the grid groove, the walls of the grid groove concerned as well as the end 36 of the tongue 37 of the door frame after the latter has been inserted in the grid groove. Furthermore. the door frame has tongues 39 and 41 which are received by the groove grid and the groove on the underside of an anchoring element respectively.
As shown in FIG. 7, a number of floor elements dc fining plate-like elements may each be combined into a major floor element 38 thereby reducing the time taken in assembling a like number of individual floor elements. By reason of the grid configuration, further major elements as well as individual floor elements may be connected to these major elements.
As shown in FIG. I, the anchoring elements have different lengths and configurations: the L-shaped elements 9 are used for the corners of the outer wall elements 4., their ends being provided with dovetail grooves and dovetail tongues respectively, which are positively connected to dovetail tongues and dovetail grooves respectively of adjacent anchoring elements. The anchoring elements are of twice the grid length and are mounted on two aligned adjacent outer wall elements 4.
The T-shaped anchoring element referenced 11 in FIG. 8 has ends which are complementary to the element referenced 11 in FIG. 1 and, in the same way as the latter. serves to fix the inner wall element 42 (FIG. 8) in its position relative to the outer wall element 4. For this purpose L-shaped anchoring elements 43 may also be provided, which have a dovetail groove 44. Ref erence 42' designates a wall element of half the grid length, which makes it possible, for example, to transpose the door of FIG. 7 by half the grid length.
FIG. 9 shows the anchoring element 5 of FIG. 1 to an enlarged scale. It has a tongue 5 which is received by the groove 45 on the underside of the marginal fillet 46 of the ceiling surface 47.
The height of the wall elements is such that it corre sponds to the height of the anchoring frame of the lowest height of the storey reproduced to scale. For the purpose of producing models of taller storeys as well, the set of building elements has wall crown elements 48, (see FIG. 10), whose length is equal to an elementary grid length or a multiple thereof and whose wall thickness is the same as that of the wall elements. On their undersides they have grooves 49 by which they are mounted on the tongues of the wall elements or the next wall crown element, and on their upper sides tongues 50, by which they engage the grooves on the undersides of the anchoring elements. Thus a plurality of these wall crown elements may be arranged one above the other, so that models of different storey heights may be produced.
11 shows the flat roof of a bungalow. It consists ofa ceiling surface 51 on the marginal fillets 53 and 54 ofwh ich parapet elements 55 and 56 are mounted. The Y parapet element 55 consists of an L-shaped fillet, a tongue 58 extending parallel to the upright section 57 and provided on the inside of the leg section, which en gages the grid groove formed by the marginal fillet and the ceiling surface 51 at the margin. The length of the two sections is such that on the one hand the marginal fillet and on the other hand the grid groove are overlapped. The parapet element 56 consists of two relatively angled adjacent parapet fillets 55, the length of each of whichis equal to the elementary grid length. Such elements are mounted on the corners.
The set of building elements is not limited to the quadrilateral floor elements. lDefining the floor elements, there may also be used polygonal floor elements, e.g., hexagonal ones together with triangular ones, which have to be provided on their upper sides with additional grid grooves, so that the wall elements may be arranged at right-angles to each other.
The positive interconnection of the floor elements may also be achieved by means of tongue fillets of other appropriate shapes complementary to the shape of the grooves in the edges of the floor elements, for example, where these grooves are of re-entrant T-shape, the tongue fillets would be of H-shaped cross-section. These variations, apparent to .an expert, are encompassed within the scope of the invention as is a construction of the floor elements in such a way that the margins of their upper portions are not rabbetted relative to those of the lower portions, and have semicylindrical portions, which together with those of the adjacent elements, form a grid-like arrangement of bores, in which pegs of the wall elements engage.
