Description:
A BUILDING ELEMENT DEVICE

The invention relates to a device in a body arranged to be joined to one or more adjacent bodies of a similar kind in the vertical and/or horizontal direction(s) for the formation of a composite structure, for example a wall, more particularly by at least one of the opposite surfaces of the body having the shape of a convex or concave cylinder surface and at least two opposite surfaces being provided with complementary locking elements.

Form the toy and building trades are known building blocks or bricks that are used for the construction of walls, for example, in which there are used locking elements which are to prevent relative movement between the elements after joining. LEGO ® building blocks are an example of this, in which the upper surface is provided with a number of raised portions of a circular cross-section arranged to engage, in a locking manner, complementary elements of the lower portion of an above-lying building block.

The drawbacks of building blocks and bricks for building walls etc. according to the prior art, are that the ability to form composite structures, in which the building elements are connected in both the horizontal and vertical directions, is highly limited. This involves that when the composite construction is subjected to a load having a force component perpendicular to the side surface of the composite structure, for example a lateral pressure on a wall surface, the building element could be forced out.

The invention has as its object to remedy or reduce at least one of the drawbacks of the prior art.

The object is achieved through features that are specified in the description below and in the subsequent Claims.

A body is arranged to be joinable to one or more adjacent bodies of a similar kind in the vertical and/or horizontal direction(s) for the formation of a composite structure, for example a wall, the body comprising, in a position of use, an essentially horizontal lower surface and an opposite upper surface, two opposite end surfaces and two opposite side surfaces, at least one of said surfaces of the body, preferably the lower and/or upper surface(s) having a convex or concave cylinder surface, one of the convex or concave cylinder surfaces of the body being provided with at least one projecting locking element and the opposite convex or concave cylinder surface being provided with at least one recessed locking element complementary to the projecting locking element of the opposite surface.

Both of said two opposite cylinder surfaces advantageously have the shape of a convex or concave cylinder surface.

In an alternative embodiment both cylinder surfaces of the body have the shape of a convex cylinder surface.

In a further alternative embodiment both cylinder surfaces of the body have the shape of a concave cylinder surface.

In yet a further alternative embodiment one of the cylinder surfaces of the body has the shape of a convex cylinder surface, and the other of the cylinder surfaces of the body has the shape of a concave cylinder surface.

Each of the projecting locking elements and the complementary locking elements advantageously extends along the periphery of the cylinder surfaces and perpendicularly to the central axis of the cylinder surface.

The projecting locking element and the complementary locking element are advantageously arranged to be joined by a body being moved slidingly along the curvature of the opposite cylinder surface of an adjacent body.

One of the end surfaces of the body is advantageously provided with at least one projecting locking element, and the opposite end surface of the body is provided with at least one locking element complementary to the projecting locking element of the opposite end surface.

The projecting locking element of each of the end surfaces and the complementary locking element advantageously extend along the end surfaces with a radius of curvature equal to the distance to the central axis of the cylinder surface of

the lower surface of the body and with the centre coinciding with said central axis.

The projecting locking element and the complementary recess are arranged to be joined by a body being moved slidingly along the curvature of the opposite cylinder surface of an adjacent body.

The locking elements are arranged to prevent two adjacent bodies from being movable relative to each other in a direction perpendicular to the extent of the opposite surfaces.

The invention is not limited to the surfaces that are the upper and lower surfaces in the position of use, being the surfaces exhibiting the shape of a cylinder surface, as any pair of opposite surfaces of the body may exhibit the shapes of convex or concave cylinder surfaces. Nor is the invention limited to only one pair of opposite surfaces exhibiting the shape of a cylinder surface, as two or more pairs of opposite surfaces of the body may also exhibit the shapes of convex or concave cylinder surfaces.

In what follows, is described a non-limiting example of a preferred embodiment which is visualized in the accompanying drawings, in which:

Figure 1 shows in perspective a body having a convex upper surface and a concave lower surface;

Figure 2a shows a ground plan of the body according to Figure 1;

Figure 2b shows a side view of the body according to Figure 1;

Figure 3 shows in perspective and on a smaller scale a composite structure formed by several bodies according to Figure 1; and

Figure 4 shows in perspective and on a smaller scale, an overlapping body, the building length being twice as large as that of the body shown in Figure 1.

Reference is made essentially to figures 1, 2a and 2b, in which the number 1 refers to a cube-like body 1 having a convex, lower cylinder surface 3, a concave, upper cylinder surface 5 complementary to the lower cylinder surface, two opposite plane end surfaces 7, 9 and two opposite, plane side surfaces 11, 13.

The lower cylinder surface 3 is provided with a locking element 15 in the form of a groove 17 having a dove-tail- profiled cross-section 19. The groove 17 follows the periphery of the cylinder surface 3 having a radius of curvature with its centre on the central axis of the cylinder surface 3.

The upper cylinder surface 5 is provided with a locking element 21 complementary to the locking element 15 of the lower cylinder surface 3, that is to say, in the form of a rib 23 having a dove-tail-profiled cross-section 25. The rib 23 follows the periphery of the cylinder surface 5 with a radius of curvature with its centre on the central axis of the cylinder surface 5.

The end surface 7 is provided with a locking element 27 in the form of a groove corresponding to the groove 15. The locking element 27 has a radius of curvature with its centre coinciding with the central axis of the lower cylinder surface 3. Correspondingly, the opposite end surface 9 is provided with a complementary locking element 29 in the form of a rib corresponding to the rib 21.

In a corresponding manner to that of the end surface 7, the side surface 11 is provided with a locking element 31 in the form of a groove corresponding to the groove 15. The locking element 31 has a radius of curvature equal to the radius of curvature of the locking element 27. Correspondingly, the opposite side surface 13 is provided with a complementary locking element 33 in the form of a rib corresponding to the rib 21.

The central lines of the locking elements 27, 29, 31, 33 all have the same distance M from a lower, straight side edge 35a, 35b.

An alternative embodiment is shown in figure 4, in which a body 51 has side surfaces 61, 63 having a horizontal extent twice as large as that of the body 1 shown in figures 1-3. Thereby, the body 51 can extend across two bodies 1. The body 51 exhibits end surfaces 7, 9 of the same shape and size as those of the body 1. Likewise, the locking elements 65, respectively 71, 77, 79 are of the same shape as the locking elements 15, respectively 21, 27, 29 of the body 1. Lower and upper cylinder surfaces 53, 55 each include two locking elements 65 and 71, respectively, with a centre spacing corresponding to the length of the straight side edges 35a, 35b of the body 1.

In the joining of several elements 1, 51, a body 1, 51 is moved in a sliding movement on one or more underlying bodies 1, 51, with the lower cylinder surface 3, 53 of the body 1, 51 gliding on the upper cylinder surface 5, 55 of the underlying body (bodies) 1, 51. At the same time, the locking element (s) 15, 65 of the body 1, 51 is (are) joined to the locking element (s) 21, 71 of the underlying body (bodies), and the locking element 27, 77 at the end surface of the body 1, 51 is joined to the locking element 29, 79 of the possibly adjacent body 1, 51, possibly, in an opposite direction of installation, the locking element 29, 79 at the end surface of the body 1, 51 is joined to the locking element 27, 77 of the adjacent body 1, 51.

In a branching, as is shown in figure 3, the bodies 1, 51 which are to form the projecting, transversal structure, are connected to the bodies 1 in the longitudinal structure by connection of the locking elements 27, alternatively 29 of the bodies 1, 51 of the transversal structure to the locking elements 33, alternatively 31 of the bodies 1 of the longitudinal structure.

It is advantageous that foundation bodies (not shown) are used, which are provided with a plane lower surface and end surfaces without locking elements.

The invention is not limited to bodies of an approximately cubic shape, possibly of a building length corresponding to an integer multiple of the building length of the cubic body 1 shown, for example the body 51 shown, but could also comprise other shapes in order to form the desired constructional structures, for example corner shapes

different from rectangular, altered wall thicknesses, transitional elements for joining floors etc.

The invention also comprises loose locking profiles (not shown) , which are suitable for joining two bodies 1, 51 placed with the locking element 27, 77 facing the locking element 31.
