Definitions

  • the present invention relates to building units for building kits or the like which units are intended to be joined manually, and without auxiliary means or tools, into larger systems, in plan as well as in space.
  • the essence of the invention resides in the feature that the building units along one or more of their edges are provided with specifically shaped interlock or coupling devices by means of which the units are joined, simply by said interlock-devices being pushed together, whereby the units arrive at a stable interengagement.
  • Building units of a similar kind are known, which are adapted to be joined along their edges by various gripping means, but these previous building units have in common that the necessary interlock or locking efiect of the grip ping means in the joined condition of the units is unsatisfactory in one respect or another.
  • the interlockdevice may be complicated, particularly by the occurrence of separate latch members or the like, and the locking engagement may be on the one handor in time betoo loose and weak or, on the other hand, too positive so that forces unnecessarily great and wearing are requested for the manipulation of the units.
  • the invention has for its object to provide a building unit of the kind under consideration, more particularly to provide locking means or interlock-devices for such building units which are simple as well as present a reliable and reasonably firm locking engagement when the units are moved together to be united.
  • the object is attained and a building unit is provided, wherein the inconveniences indicated above of prior similar building units are eliminated by the building unit according to the invention obtaining the characteristics defined in claim 1.
  • FIG. '1 is a perspective view of two building units of a simple design which are provided along their opposing edges with each its interlockdevice according to the invention.
  • FIG. 1a shows one of these units in another perspective
  • FIG. 2 is a perspective view of both units in a position pushed together under mutual engagement.
  • FIG. 3 is a plan view of a part of the interlock-device of one of the building units shown in FIG. 1.
  • FIG.4 is a perspective view of a tooth component of an interlock-device for building units according to the invention, including the adjacent surroundings of said tooth
  • FIG. 5 is a cross-section along the line VV in FIG. 4, while FIG.
  • FIG. 6 is a section corresponding to that shown in FIG. 5 but through to interengaging interlock-devices having teeth according to FIG. 4.
  • FIGS. 7 and 8 are fragmentary cross-sections through interengaging teeth component of interlockdevices according to the invention, the sections being taken at right angles to the longitudinal direction of the edge of the devices, the figures illustrating alternative forms of the interengaging surfaces.
  • FIG.9 is a view corresponding to FIG. 4 but shows a tooth component of an interlock-device according to FIG. 8
  • FIGS. 10 and 11 are fragmentary plan views of alternative designs of the plan form or profile of the teeth component of the interlock-devices according to the invention.
  • FIG. 12 is a perspective -view of a portion of an interlock-device having the tooth profile shown in FIG. 11.
  • FIGS. 13 and 14 are fragmentary plan views illustrating two steps in a particular case of mounting the building units according to the invention and FIG. 15 finally shows a perspective view of a building unit according to the invention, more particularly an angular piece provided with two interlockdevices perpendicular to one another.
  • FIG. 1 a pair of building units 10 according to the invention which are provided along two opposing edges with interlock-devices according to the invention.
  • the interlock-devices of the units are identical, for which reason corresponding details of the two interlock-devices have been provided with the same reference characters.
  • the units comprise flat, uniformly thick, rectangular plates having along their interlock edges rows of teeth 12, 14, 16, 18, which between themselves have tooth spaces, said spaces and the teeth having identical plan forms, that is, their rojections in plan are identical.
  • each tooth may be considered as a flat, uniformly thick projection on the plate, having a thickness equal to half of that of the plate.
  • the mutually identical teeth are in this case defined by straight peripheral edges 20, 22, 24, see FIG. 3, whose projections in plan form a right angle to each other and exhibit together the profile or plan form of the teeth; thus in this case an isosceles right-angled triangle.
  • the edges of the teeth will of course define at the same time the tooth spaces, and thus it follows from the above stated that also the space profile has the form of an 3 isosceles right-angled triangle in agreement with the tooth profile.
  • a common pitch line 28 may be defined for the two adjacent or contiguous tooth rows as a straight line extending in the common plane, that is the medial plane, of the two tooth rows, the pitch line halving the edges 20, 22 etc. of the teeth or, more correctly, the projections in the medial plane of said edges.
  • the pitch t of the teeth is represented by the distance between two subsequent, equally oriented or situated intersections between the pitch line and the tooth profile, see FIG. 2.
  • the interlock-device disclosed above is capable of fixing the building units in their mutual position shown in FIG. 2, and in this position it is able to transmit forces perpendicular to the medial plane of the joint and bending and turning moments about axes in this plan.
  • the prerequisite hereof is that at least four teeth are components of each interlock-device and are engaging each other. If one or both interlock-devices contain an odd number of teeth the same position may be attained by means of only three teeth in engagement.
  • FIG. 4 shows a perspective view, as seen obliquely from above, of a tooth 34 in the one tooth row together with teeth 36 and 38 in the other row, which thus is offset in relation to the first row of teeth.
  • Teeth belonging to the one interlock-device will crow by its insides the opposite insides of teeth component of the opposite interlock-device, and by the compression force caused hereby a connecting friction force is created between the devices. But the difference in level or thickness caused by said crowding and occurring in the joint is imperceptible in practice; by way of illustration the measure 5 has been strongly exaggerated in the figures.
  • Theprotuberance 40 on the insides of the teeth may be formed in a plurality of dilferent ways. First and foremost the thickening or protuberance may be uniformly distributed across the whole exposed inside of the tooth so that an even engagement takes place over the whole contact surfaces of the teeth. Further, the protuberance may be locally restricted and shaped as low bosses, ribs and the like which meet and press against each other when the interlock-devices of the building units are pushed together.
  • the inside of the tooth may also be fluted or patterned and, finally, the protuberances may be shaped in such a way that they form interengaging hooks which permanently locks the joined interlockdevices.
  • FIG. 7 shows a section perpendicular to the longitudinal direction of the interlock-device, e.g. through the device shown in FIG. 2.
  • the locking action is of the type known as snap-locking, that is, the teeth 44 of the device are in this case provided with protuberances in the form of bosses or ribs 46 adapted to engage into depressions in the form of small pits or grooves 48 the protuberances and depressions being so located on the insides of the teeth that they will engage in pairs with each other in the locking position of the devices, as may be clearly seen in FIG. 7.
  • FIG. 7 represents a section analogous to that shown in FIG. 7 but illustrates how a protuberance 50 near the base of the teeth 54 merges continuously into a depression 52 near the apexes of the teeth so that the insides of the teeth will interengage in locking position, as shown in FIG. 8.
  • the inside of a tooth 54 will then appear approximately as shown in FIG. 9.
  • the teeth of the interlock-devices are preferably bevelled or rounded at 35, see FIG. 4, along the outer edges of the insides or at least along a part of these edges, particularly at the apexes of the teeth.
  • the interlock-devices seek each other at the initial pushing together, this operation, as described above, being terminated by the portions of the insides of the teeth within the bevelled edges entering in one way or another into a strong frictional interengagement during a simultaneous slight elastic deformation of the teeth.
  • Said bevelled edges may form 45 or some other suitable angle to the medial plane and may be provided on all teeth or on the teeth of one row only.
  • the other tooth forms described may bevelled as shown at 45 in FIG. 7 and at 55 in FIGS. 8 and 9.
  • such bevelling of the teeth is not always necessary; in certain cases, particularly in small teeth, the mounting may be carried out quite readily even with no bevels being provided.
  • the plan form or profile of the teeth and the tooth spaces may be modified within certain limits in various ways, for instance, as shown in FIGS. 10 and 11.
  • the apexes of the teeth and thus (in accordance with the basic condition of identity between the plan form of the teeth and tooth spaces) the bottoms of the tooth spaces have been cut oif, straight portions 58 and 60, respectively, being left at the same distance from the pitch line 62.
  • the plan form has not been changed.
  • the apxes may be rounded or the profiles of the teeth and the tooth spaces may together form a wave line, approximately as indicated in FIG. 11.
  • the apex angle or, according to the invention an interesting limit condition holds for this angle, viz, it may be greater than but not less than as will be discussed in greater detail below.
  • the apex angle in this figure denoted will be the angle between tangents to the profile curve 64, 66 at its points of inflexion that is, at the point 67 of intersection with the pitch line 68.
  • this may have an arbitrary geometrical form.
  • bevelling of the teeth in tooth forms according to FIGS. and 11 it may sufiice to bevel along the tooth apexes parallel to the pitch line, as indicated at 70 and 72, but of course bevelling may also be extended along the projecting or exposed part of the teeth, as shown at 65 in FIG. 12, which in other respects illustrates an interlockdevice having a tooth profile according to FIG. 11.
  • the above mentioned limit condition of the apex angle on or a relates to the conditions prevailing in uniting, on the one hand building units exhibiting at least two mutually perpendicular edges provided with interlock-devices and forming an indenting corner and, on the other, building units having right-angled edges intended to be fitted in into said corner, as illustrated in FIGS. 13 and 14. It will be readily appreciated that such a case of mounting will be frequently occurring in joining together units into larger areas.
  • a building unit 74 has as its lower left corner, as viewed in the figures, two interlock-devices whose pitch lines 80' and 8 2 intersect at right angles in the point 84, which thus forms the end point of the tooth rows along the lower edge of the unit 74 as well as of the tooth rows along the left edge of the unit.
  • a second building unit 78 has a lower right corner formed in the corresponding way and is joined along its lower edge to the upper edge, provided with interlock-devices, of a third building unit 76.
  • the last mentioned edge continues beyond the unit 78, and thus an internal right-angled corner is formed between the two last mentioned units, and the sides of this corner are formed by the interlock-devices of the respective units, said devices comprising tooth rows according to the above, and which rows have pitch lines 86 and 88. intersecting in a point 90.
  • the units 74 with the external corner may be pushed quite simply into the internal corner in the direction of arrow 92, that is, along the bisector 94 of the last mentioned corner; in other words, the pushing direction forms 45 to the direction of the interlock-devices.
  • FIG. 14 the situation is illustrated when the pushing together has been carried through half ways, and it is terminated by the intersection points 84 and 90 of the pitch lines of the respective interlock-devices of the units coinciding.
  • the three building units form, in the manner presumed, a common smooth wall surface. From FIGS.
  • the apex angle of the teeth has to be at least 90; at smaller apex angles the teeth will collide and their flanks cannot slide past each other.
  • teeth and tooth spaces of the interlock-device being formed in the manner specified building units of rectangular or square form and provided with interlockdevices along some or all edges may thus be joined in any order when larger planes or plates are joined. As indicated above joining in corners occurring is further facilitated if the apex angle of the teeth is chosen larger than 90, and if the teeth are formed with truncated or rounded apexes according to FIGS. 10 and 11, respectively.
  • interlock-devices according to the invention may also be arranged on a building unit in such a way that their medial planes do not coincide with each other or with the medial plane of the main body of the units.
  • FIG. 15 shows e.g. an angular building unit having two interlock-devices whose medial planes 96 and 98 are perpendicular to one another, thereby rendering it possible to build three-dimensional objects, as is requested in putting up model buildings and the like.
  • interlock-device portions of a building unit which lies Within or at the side of the interlock-device or devices may be arbitrarily formed, for instance, as fiat surfaces with materialsaving recesses, curved surfaces, frame structures or latticeworks and so on. Neither is it necessary that an interlock-device extends along the whole side or edge of a building unit but it may be divided into two or more sections separated by even or straight portions without teeth.
  • a building unit according to claim 1 wherein said protuberances are uniformly distributed across the whole exposed inside of the associated teeth so that a uniform engagement takes place across the whole contact surfaces of the teeth when the interlock-devices are joined.
  • a building unit according to claim 1 characterized in that the protuberance on the inside of the tooth surface corresponds to a depression in the opposing tooth inside surface so that any protuberance engages into a corresponding depression when the interlock-devices are joined.
  • a building unit according to claim 1 having said interlock-devices along at least two of its edges, wherein the dividing planes of the respective interlock-devices form a certain angle to one another.
  • a building unit according to claim 1 characterized in that the teeth have a truncated form, that is, their apexes are cut off straight, parallel to the direction of the tooth row, the tooth spaces being provided with corresponding straight or fiat bottoms.
