    ELONGATE BAND FORMING A BASE OF BUILDING GAME BLOCKS
    REFERENCE TO ASSOCIATED REQUESTS
    The present application claims priority over the British patent application number 1619927.5 filed on November 24, 2016 and over the South African provisional patent application number 2017/04276 filed on June 23, 2017.
    FIELD OF THE INVENTION
    The present invention relates to an elongated strip forming a base of building play blocks and, more particularly, an elongated strip which is compatible with existing substantially rigid building play blocks.
    Existing building game blocks can include many variations, but generally include at least elementary building blocks which are rectangular parallelepipedal in shape with multiple projections extending from a surface which can be considered the male mating surface and an opposite female mating surface. The male mating surface generally forms an upper surface in use, and the female mating surface a lower surface so that the blocks can be frictionally engaged or clipped with compatible building blocks to form structures of a selected size and shape.
    Typically, two rows of picked up protrusions or receiving recesses are provided across a surface of a standard full width building block while a single row of picked up protrusions or receiving recesses is provided on the surface of a standard half-width building block. The lengths of a standard full-width building block and a standard half-width building block generally vary from one to eight picked up projections or one to eight receiving recesses in length and may go up to sixteen, which is the longest known to the claimant. Many special external forms of building blocks are provided to create replicas of people, figurines, characters and structures, but these all, as a rule, have protrusions and recesses cooperating to allow their temporary connection with the basic building blocks.
    BACKGROUND OF THE INVENTION
    Generally, the protrusions of building play blocks are roughly cylindrical picked projections arranged in aligned rows extending over a length of the building block and the recesses are formed by a space between the side and end walls d a shallow block and one or more surfaces of interlocking formations such as cylindrical formations extending from an interior of an upper wall of the block to a lower surface plane of the block. The picked up projections are, under operating condition, engaged by the interior surface of the side walls and any adjacent end walls and a surface of the interlocking formations. The side walls and end walls are smooth, except for specialized building blocks.
    The most common range of building blocks of this general nature, as far as the applicant is aware, is probably that sold under the trade name LEGO®, which is a registered trademark of LEGO JURIS A / S, a Danish company. However, there are other compatible building blocks available such as MEGA BLOKS®, a trademark of MEGA BLOK INC, a Canadian company (which works with MATTEL® and FISHER PRICE®) and KRE-O building blocks ® marketed by HASBRO®, a Korean company.
    It should be noted that the scope of the present invention is not to be construed in any way as being limited to use in conjunction with any particular range of building blocks, and the basics of the present invention can be used with any of the above or any other types of building blocks of the same general nature, or even as part of a set of custom building blocks.
    State-of-the-art building block sets allow replicas of people, figurines, characters and structures to be constructed relative to each other in the form of a separate base sheet having formations thereon to receive building blocks in friction or clipping relation to the base sheet. These base sheets are standard sizes and the base sheet sizes to be used are limited in number and must be selected or acquired depending on the purpose.
    Likewise, 10 inch (254 mm) by 10 inch (254 mm) square adhesive “LEGO® compatible bricks” are available on the market, which have on their surface facing a network of formations adapted to receive play blocks. construction of the general type described above so that a complete structure can be built on one or a plurality of aligned bricks juxtaposed. The bricks have numerous projections arranged so that an edge-to-edge location of the bricks results in a continuous series of formations being created on the surface at the connections between the bricks on a surface to which the bricks are bonded. using an adhesive with the outer edges aligned. The adhesive is self-adhesive and selected so that the bricks can be fixed by detachable gluing to any suitable support surface and can be used to support replicas of people, characters and structures, the bricks being glued, for example, on a window, a wall, a piece of furniture, the surface of a device or the surface of a computer, just as an example.
    MEGA BLOK INC® also provides a base which consists of a number of coplanar sections hingedly attached to each other so that a composite flat base of different peripheral shapes can be created.
    The modularity of the building blocks of the general nature described above has been exceptionally successful. However, these types of prior art bases are restrictive regarding certain types of creations which can be applied to them in particular circumstances.
    From the point of view of the published state of the art, EP 0621062 A2 by Messerschmitt describes a flexible base similar to a sheet which can have various profiles. However, he does not envision profiles that can twist and turn and would be unsuitable for these applications.
    US9480931 from Samo & Elliott describes a variety of different bases, both rigid and flexible, incorporating at least one elongated element embedded in the base and made of a material different from that of the base.
    DE202013104194 from Sailer describes a floor covering which is not designed to have any profile other than flat ground and therefore cannot twist or turn.
    EP 3005894 of Capboytrading describes a cap having an apex and optionally a display plate on the cap having a network of multiple cylindrical projections to which the building play blocks can be fixed in the manner indicated above. There is nothing to suggest that such a base could have a twisting and turning profile.
    The foregoing discussion of the background of the invention is intended only to facilitate understanding of the present invention. It should be emphasized that the discussion does not recognize or admit that any of the materials mentioned were part of the general knowledge of the state of the art as of the priority date of the request.
    SUMMARY OF THE INVENTION
    According to a first aspect of the present invention, a base of building play blocks comprising a flexible elongated body strip having a first main surface along a length of the strip is provided. It comprises either a network of projections extending from the first main surface or a network of recesses defined in the first main surface, the projections or recesses forming a coupling arrangement for cooperating building blocks, the strip of body having a second opposite main surface which is flat or has at least one shallow flat bottom longitudinal recess in both cases with a longitudinal adhesive layer by which the body strip can be attached to a support surface, in which the body strip has a maximum of four projections or recesses over its width and has a length of at least 200 mm, the entire body strip being made of a homogeneous flexible material with a durometer value of between 35 and 80 depending on the ASTM D2240 type A durometer scale.
    Other characteristics provide that the body strip has a width of between 12 mm and 40 mm and comprises two, three or four protrusions or recesses over its width, preferably only two protrusions or recesses; and that the body strip has a thickness defined between the first main surface and the second main surface of between 1 mm and 6 mm, preferably between 2.5 mm and 4.4 mm.
    Other characteristics provide that the adhesive layer is a preformed adhesive layer applied to the base of building play blocks, preferably in a longitudinal recess with a shallow flat bottom of housing receiving a main part of the thickness of the adhesive layer. preformed. The preformed adhesive layer may be a double-sided adhesive polyurethane strip and may comprise a removable covering strip on an exposed face while awaiting initial use; and may be of a reusable type to allow the base of building blocks to be detached from a surface to which it is bonded and then to be bonded to another surface in a reusable manner. If the body strip has a shallow flat bottom longitudinal recess, the adhesive layer may have a thickness between 0.4 mm and 0.8 mm, and the longitudinal recess may have a depth so that an exposed face of the adhesive layer is slightly in front of the edges of the elongated body strip.
    The base of building blocks can have a length in the range between 200 mm and 3000 mm, and preferably between 500 mm and 2500 mm; and can be produced as an extrusion of indefinite length which is divided into selected lengths.
    Other features provide that the width of the base of building blocks can be selected to be the same as that of standard building blocks in association with which it is intended to be used; and that the durometer value of the flexible material is between 45 and 65 with preferred values between 50 and 60. The base of building blocks can be divided by cutting it with a cutting instrument such as a pair of household scissors.
    If the body strip includes an array of regularly spaced recesses defined in the first main surface, each recess may be formed by multiple surface areas designed to engage portions of an outer peripheral surface of a projection of a building block received intermittently inside thereof around the peripheral surface of the projection.
    If the body strip comprises a network of regularly spaced projections extending from the first main surface, each projection may have a diameter which is slightly greater than a corresponding recess in a cooperating play block so that the projection is deformed when pushed into a corresponding recess to create friction interference between the protrusion and the cooperating play block; so that the projections are cylindrical projections; and so that each projection has a flat top and a beveled or rounded edge between its cylindrical side wall and its flat top to guide the projection into the corresponding recess. In one example, the projections have an effective outside diameter of 4.95 mm (+/- 0.5 mm), a radius of 0.5 mm on the beveled or rounded edge, and a height of 1.8 mm, and are designed to cooperate with building blocks that have 4.8 mm diameter recesses.
    Other features provide that the first main surface of the body strip includes guide lines which assist a user in cutting the body strip with a cutting instrument such as a pair of scissors. The guide lines may include a set of parallel transverse guide lines that extend at least in part across the width of the body strip at regularly spaced intervals between adjacent sets of projections or recesses to assist a user to make a cut across the width of the body strip at right angles to the length of the strip. The evenly spaced intervals may be located between each adjacent portion along the length of the body strip. The guide lines may also include one or more longitudinal guide lines which extend between rows of protrusions or recesses along the length of the body strip to assist a user in cutting along the length of the body strip. body.
    The guide lines can be formed by grooves in the first main surface of the body strip, and each guide line can include a set of aligned grooves. Each groove in the groove set can coincide with a projection or recess so that ease of cutting with a cutting instrument such as a pair of scissors changes each time a user cuts a distance associated with a projection or a recess.
    The base of building blocks can be sold in bulk packages; individually wrapped; or in the form of rolls or loop coils thereof of predetermined length.
    The material from which the base of the building blocks is made preferably has a weak plastic memory and more preferably has no plastic memory. The base of building blocks can be made from a plastic material, and the plastic material can be selected from thermoplastic rubber (TPR) or from polymeric organic silicone compounds often called silicones. These plastic materials can be deformable enough to bend but rigid enough to support building play blocks by mutual engagement of the protrusions and recesses of the base of construction play blocks with cooperating recesses or protrusions. a generally rigid building block.
    The material may also be a pulp product which is presented in a flexible matrix exhibiting suitable flexibility properties. A sprayed or powdered cork product that comes in a flexible matrix can also be used.

    DETAILED DESCRIPTION WITH REFERENCE TO DRAWINGS
    Figures 1 to 8 show an embodiment of a building block base (10) according to the invention. The base of building play blocks (10) is in the form of a flexible elongated body strip (12) having a first main surface (14) along a length of the strip with a network of projections (16) s extending from the first main surface (14).
    The building block base (10) is intended to be used in combination with generally rigid building block blocks (50, 52), two variants of which are shown in Figures 10 to 13, or other cooperating blocks special types, such as those sold under the trade designation LEGO®. These building blocks (50, 52) have at least one flat surface (54), usually used as an upper surface, with numerous projections (56) forming a male mating surface, and a network of recesses (58 ) which form a female mating surface having a surface plane from which the recesses extend inward and usually form a bottom surface. Different building play blocks (50, 52) can be frictionally engaged or clipped with compatible building blocks (50, 52), at least a portion of the many protrusions (56) engaging in female recesses at less partially covered (58) with another building block (50, 52) to form structures of a selected size, shape and configuration.
    Returning to Figures 1 to 8, the first main surface (14) of the building block base (10) is an otherwise flat surface so that the network of projections (16) defines a male coupling arrangement for cooperating building play blocks (50, 52). In this embodiment, the protrusions (16) are straight circular cylindrical protrusions picked up evenly spaced in adjacent aligned pairs in two parallel rows along the length of the flexible elongate body strip (12) so that the strip comprises two projections (16) across its width. The flexible elongated body strip (12) has a width corresponding to the width of a single standard building block (50, 52) which may, for example, be 15.8 mm. However, the invention is not limited to this width, and the width can vary between 12 mm and 40 mm with two, three or four protrusions across the width.
    A second opposite main surface (18) of the strip has, as shown in Figure 3, a pressure-sensitive adhesive (20) which can secure the base of building play blocks (10) to a flat or raised surface. The pressure-sensitive adhesive (20) is covered with a removable cover strip (22) on an exposed side of the adhesive (20) pending initial use. The pressure-sensitive adhesive (20) is preferably of a detachable type in order to allow the repositioning of the base of building play blocks (24) on a support surface provided for this purpose. This may allow the building block base (10) to be detached from a support surface to which it is glued and then to be glued to another surface in a reusable manner.
    The adhesive (20) can be applied directly to the base of building blocks (10), but preferably consists of one side of a pre-formed adhesive layer (26) applied to the base of blocks of building blocks construction (10) during or after manufacture, as shown in Figure 7. The second main surface (18) of the building block base (10) may be flat, in which case the adhesive (20) only, or the preformed adhesive layer (26) can be applied to the second flat main surface (18). In the illustrated embodiment, however, the adhesive layer (26) is located in a shallow flat bottom longitudinal recess (28) in the second main surface (18) of the base of building play blocks (10). Even if only one shallow flat bottom longitudinal recess (28) is illustrated in these embodiments, it will be appreciated that two or more shallow flat bottom longitudinal recesses may extend side by side along the length of the body strip. , or a number of separate recesses can be formed with bracing portions which extend at regular intervals along the length of the body strip.
    The adhesive used to attach the adhesive layer (26) to the base of building blocks can be the same as that to fix the base of building blocks to a support surface and it can be applied before the adhesive layer (26) is applied to the base of building play blocks (10) due to its manufacture. In one embodiment, the adhesive layer (26) is applied as one side of a double-sided adhesive polyurethane tape which is located in the shallow flat bottom longitudinal recess (28), the depth of which is such that the longitudinal recess with shallow flat bottom (28) receives a main portion of the thickness of the adhesive layer (26) and an exposed face (30) of the adhesive layer is slightly in front of the edges (32) of the body strip elongated (12) extending along each side of the shallow flat bottom longitudinal recess (28), as illustrated in Figure 7. The adhesive layer (26) may have a thickness of between 0.4 mm and 0.8 mm, the depth of the flat bottom longitudinal recess (28) being slightly less than the thickness of the adhesive layer (26), for example between 0.3 mm and 0.7 mm. The adhesive layer (26) and the flat bottom longitudinal recess (28) are also narrower than the width of the body strip (12) so that the edges (32) form shoulders. The shoulders assist a user to separate the base of building play blocks (10) from a surface to which it is attached from the side with a finger to bend the material of the body strip (12) along one side of the strip (12).
    Each projection (16) may have a diameter which is slightly greater than a corresponding recess (58) in a cooperating play block (50, 52) so that the projection (16) deforms when it is pushed into a corresponding recess (58) to create friction interference between the protrusion and the cooperating play block to hold the play block in engagement with the base of building play blocks when glued to a vertical or elevated support surface . It is desirable to be able to support not only one block, but a complete set of blocks created from interconnected blocks. In this embodiment, the projections (16) are cylindrical projections, each projection having a flat top (60) and a rounded edge (62) between its cylindrical wall (64) and its flat top (60) to guide the projection. (16) in the corresponding recess (58). In other embodiments, the edge may be beveled rather than rounded. Simply by way of example, in a product design, the protrusions have an effective outside diameter of 4.95 mm (+/- 0.5 mm), a radius of 0.5 mm on the rounded edge, and a height 1.8mm to provide a surface area around the outside of the projection which helps provide a surface friction force which helps to keep the block in engagement with the base of building play blocks (10). These projections (16) are designed to be received in a corresponding recess (58) of a block (50, 52) having an effective diameter of 4.8 mm. This means that, in this case, the effective diameter of the projection is approximately 3% greater than the effective diameter of the recess, but a wider range between 2 and 5% is also envisaged.
    In these embodiments of the invention, the engaging projections (16) are circular in plan, but in other embodiments, they may be of a different shape in a plan view such as a square shape. or symmetrical cruciform. The important thing is that the effective diameter of a projection is slightly greater than the effective diameter of a receiving recess, and a bevelled or rounded upper edge "leading" of a projection is necessary to help guide the projection in a receiving recess.
    The complete flexible elongated body strip (12) of the base of building play blocks (10) is made from a homogeneous flexible plastic material such as thermoplastic rubber (TPR) or a polymeric organic silicone compound often called silicone . The material preferably has a weak plastic memory and more preferably no plastic memory. This material is deformable enough to bend but rigid enough to support a large, suitable set of building play blocks (50, 52) by mutually engaging the projections (16) of the play block base of construction with cooperating recesses (58) of one or more generally rigid building play blocks (50, 52). The building block base (10) is also flexible so that it can bend to follow a three-dimensional profile when attached to a support surface or structure having a profile other than flat while retaining its Ability to support many building play blocks (50, 52) or other compatible blocks of a special shape. A durometer value of the flexible plastic material between 35 and 80 is a target range with a preferred value between 45 and 65 and more preferably between 50 and 60, according to the type A durometer scale of the D2240 standard. ASTM (American Society for Testing and Materials). These durometer values allow the body strip (12) to be divided using a cutting instrument such as a pair of household scissors. The profile can twist and turn to an extent compatible with the positioning of any generally rigid building play blocks (50, 52) which are to be attached thereto.
    Other materials which can be used for the flexible elongated body strip (12) include a pulp product which is presented in a flexible matrix having suitable flexibility properties, or a pulverized or powdered cork product which present in a flexible matrix.
    The base of building play blocks can be of different lengths generally in the range of 200mm to 3000mm, and preferably between 500mm and 2500mm. If the width of the base of building blocks is a known width of 15.8 mm, a length of one meter would correspond to a width / length ratio of 1:63 for a length of about one meter; 1: 126 for a length of about two meters; and a ratio of 1:30 for a length just under half a meter.
    Regarding thickness, the base of building play blocks (10) has a thickness which corresponds to the distance between the first and second main surfaces (14, 18), which is at least to a large extent dependent on the material of manufacture and is preferably between 1 mm and 6 mm, and more preferably between 2.5 mm and 4.4 mm. The thickness is selected primarily so that the base of building play blocks (10) is flexible enough so that it can bend to follow a three-dimensional profile in bending and twisting when attached to a support surface or a structure having a profile other than flat. The building block base must, however, retain its ability to support cooperating building blocks and other cooperating specially shaped blocks through mutual engagement of male and female mating surfaces without the risk that they separate easily. The thickness is greater than the height of the cylindrical projections (16) above the flat surface. It will be fairly obvious that the thickness is also determined by the sharpness of the curvature which must be applied to the base of building blocks without excessively distorting the arrangement of the projections or recesses so that they retain their functionality.
    The first main surface (14) of the flexible elongated body strip (12) may include guide lines (36) that assist a user in cutting the body strip with a cutting instrument such as a pair of scissors. The guide lines (36) are shown more clearly in Figure 5 and include a set of parallel transverse guide lines (38) which extend across the majority of the width of the body strip (12) at intervals spaced evenly between adjacent sets of protrusions (16) to assist a user in cutting across the width of the body strip (12) at right angles to the length of the strip (12). In this embodiment, the regularly spaced intervals are between each adjacent portion (16) along the length of the body strip (12), but the regularly spaced intervals can be every two, three, or four sets projections (16) or more. Each transverse guide line (38) is, in this embodiment, formed by a set of two aligned grooves (40, 42) in the first main surface (14) of the body strip (12), each groove (40 , 42) of the groove assembly (40, 42) coinciding with a projection (16) so that the ease of cutting with a cutting instrument such as a pair of household scissors changes each time a user cuts a distance associated with a projection (16).
    The guide lines (36) also include a longitudinal guide line (44) which extends between the two rows of projections (16) along the length of the body strip (12) to assist a user in cutting out the length of the body strip (12). In embodiments in which two, three or four protrusions (16) extend across the width of the body strip, longitudinal guide lines may extend between each row of protrusions (16).
    In other embodiments, the guide lines may be deeper and may even optionally weaken the material of the body strip (12) along a guide line by tearing it. Although in Figure 5 guide lines (36) are shown between each pair of protrusions (16), guide lines may be provided between any number of pairs of protrusions.
    As shown in Figure 9, the building block base (10) is designed to be used with generally rigid building block blocks (50) which may be part of a set or may be sold separately. In both cases, the structures can be manufactured in a well known manner and are based, in this case, on the basis of building play blocks (10) of the present invention.
    Certain sets of building blocks with which the building block base (10) is to be used may have rather thin building blocks (52) since some of their components are in some cases called building blocks under plate form (52). The base of building blocks (10) may in certain cases have a selected thickness so that its first main surface (14) is at the same height as that of a building block in the form of a thin plate (52) placed next to it on a common base (70) or other building block, as shown in Figure 14. A structure or set of building blocks comprising building blocks of a height standard (50) and optionally other building blocks can be designed to extend partially on the basis of building play blocks (10) and partially on a building block in the form of a juxtaposed plate (52), while remaining parallel to a support surface (70).
    This possibility gives rise to an embodiment of the invention in the form of a set of building play blocks comprising at least one base of building play blocks (10) according to the present invention as well as numerous blocks of generally rigid standard building blocks or other existing building block blocks (50, 52). The generally rigid building play blocks (50, 52) may have different lengths and heights although the basic building blocks may have two different heights for convenience of construction. For purposes of illustration and completeness of the description only, Figures 10 and 11 illustrate the top and bottom of a standard height of building block (50) which has a first flat main surface (54) can be considered an upper surface with numerous cylindrical projections (56) forming a male coupling surface compatible with those located on the basis of building blocks of the present invention. Recesses (58) form a female mating surface on an opposite second main surface plane spaced from the first main surface from which the protrusions extend a distance defining a height of the standard building block (50 ).
    The arrangement is such that a generally rigid building block (50) can be frictionally engaged or clipped with at least some other generally rigid building blocks (50, 52) with the cylindrical projections of a surface d The male coupling engaging in receiving recesses (58) in the second main surface of a compatible building block (50, 52) to form composite structures of a selected size and shape. The building block set includes at least one flexible building block base (10) as described above for optional use when required.
    It will be fairly obvious that the length of the base of building game blocks (10) can be considerable and will be chosen according to requirements and intended use, as well as the commercial and promotional strategy. Generally, the shorter lengths, say, between 320 mm and 400 mm, can be individually wrapped in packages or shells while the longer lengths can be wrapped and packaged or wrapped in shells. A base roll (72) of strip building game blocks is shown in Figure 15 while a looped reel package (74) in the form of a skein is shown in Figure 16, simply as example. As noted above, the base of building game blocks can come in many different lengths.
    The advantageous properties of building block blocks according to the present invention cannot be obtained in practice without rigorous product design. The choice of material must be such that the curvature and bending of the strip material constituting the base of building play blocks does not significantly alter the positioning and tolerance of the projections or recesses which must engage with formations. cooperating on building play blocks cooperating to the extent that the building blocks cannot be properly engaged. Likewise, it is important that the positioning and tolerance of the protrusions or recesses remain substantially unchanged after repeated deformation of the protrusions or recesses.
    Given that the materials are generally flexible elastic materials, the size and profile of the engaging projections or recesses are essential to provide the desired load-bearing characteristics of the brick for mutual engagement of the block base building block when the product supports building block blocks on a vertical support surface or suspends bricks from a high support surface.
    A test can for example be carried out to evaluate the capacity of a block to remain in engagement with the base of building blocks of play through the application of a force acting to detach the block from the base of blocks of construction game. In such an example, a base of building play blocks (10) having two rows of projections (16) across its width can be attached to the underside of a horizontal plate in height. The protrusions (16) can take the form described in certain previous embodiments given by way of example, with an effective outside diameter of 4.95 mm (+/- 0.5 mm), a radius of 0.5 mm. on the rounded edge, and a height of 1.8 mm, circular in plan. The block is attached to the base of building play blocks so as to engage eight of the projections, each being received in a corresponding recess (58) in the block which has an effective diameter of 4.8 mm. The building block can be weighted with metallic weights, so that the force of the weights acts to detach the block from its socket with the base of building play blocks. In some embodiments, tested in this way, the block can be ballasted with a weight of 415 grams, and the grip can support this load for more than 30 seconds. In some embodiments, the mutual engagement of the block and the base of building play blocks, via eight projections, can support a weight of more than 400 grams, or at least more than 300 grams, when are tested this way.
    Figure 17 shows that the base of building play blocks (10) can be attached to a support surface in a number of areas (76) along the length of the body strip (12) by contacting the layer adhesive (26) of the base of building blocks (10) with the support surface. The base of building blocks (10) is unsupported between the two or more zones (76) and the building blocks (50), or a complete set of building blocks (50) can be attached at the base of building blocks (10) between the areas (76) in the unsupported regions, so as to create a play structure supported by the base of building blocks (10). Figure 18 shows a different arrangement where a relatively short base length of building play blocks (10) is attached to two separate objects (78, 80) in areas (82) towards its free ends, a middle part of the base of building blocks (10) being unsupported and supporting one or more building blocks (50).
    Numerous variations of the building block bases are within the scope of the invention. Figures 19 and 20 show a base of building play blocks (100) which comprises a flexible elongated body strip (102) having a first main surface (104) along the length of the strip (102) which comprises a network of '' recesses (106) defined in the first main surface (104) forming a female coupling arrangement for the cooperating building play blocks (50, 52) or for cooperating with mâle male coupling arrangement of the block base construction set (10) illustrated in Figures 1 to 8. Each recess (106) can be formed by numerous surface areas designed to engage portions of the outer periphery of a projection (16, 56) of a building block (50, 52) or a base of cooperating building blocks (10) received therein discontinuously around the surface of the projection (16, 56). This version of the building block base (100) can therefore be called the female or receiving version. Like the male version, the female version of the building block base (100) includes a shallow bottom longitudinal recess (108) which receives an adhesive layer (110) including a removable cover strip (112). The joint use of male and female versions of a base of building play blocks (10, 100) offers the possibility of using them in a manner analogous to hook and loop fastening, where the adhesive of the male version can be attached to an object, the female version adhesive can be attached to a different object, and the two objects can be releasably held together by means of the cooperating projections (16) and recesses (106).
    Figure 21 shows another arrangement of recesses (122) in a different female version from the base of building play blocks (120). The female versions (100, 120) can also be useful if the user wishes to build inwards from a height or raised surface.
    Figure 22 shows another embodiment of a building block base (200) which has four projections (202) across its width so that it has four rows of longitudinally extending projections (202) to that two standard building blocks each having two rows of projections can be accommodated across the width of the base of building blocks (200) next to each other or in any other way. There are, of course, no restrictions on the orientation of the cooperating building blocks, which is dictated by their geometrical arrangement relative to each other. Three elongated guide lines (204) are included between the four rows of projections (204).
    Figure 23 shows another embodiment of a building block base (300) which is somewhat simpler and includes a simple flat bottom without a longitudinal recess. In this case, an adhesive layer can be thinner and applied directly to the flat bottom. The building block base (300) is also devoid of any guidelines.
    As an alternative to using the inherent flexibility of a single thickness of the material from which the base of building play blocks are made, and as shown in Figure 24, the thickness of the material can be reduced between selected pairs of adjacent projections. In the case illustrated in Figure 24, reduced areas (400) are provided after four pairs of projections which would correspond to a base of building blocks having four pairs of projections. These reduced thickness zones provide so-called active hinges between adjacent zones which each have four pairs of projections so that increased flexibility is offered at the active hinges with limited flexibility between adjacent active hinges. Of course, these zones of reduced thickness can simply be grooves which can, moreover, act as cutting or tearing guide lines.
    Figure 25 illustrates a basic construction of building block toys (500) in which a multitude of short lengths (502) of basic building blocks are supported by a flexible tape (504) making the base of block building blocks sufficiently flexible construction, as described above.
    Figures 26 and 27 illustrate a method of manufacturing a base of building play blocks according to an embodiment of the invention. A plastic material which has the properties described above is extruded by means of an extrusion die (601) into an extrusion (600). In this embodiment, two extrusions (600) are formed side by side. The extrusions (600) form elongated body bands (602) which are then profiled before the plastic material hardens using a roller mold (604) which supports the elongated body bands (602) to include either a network of projections (606) or a network of recesses (in the case of a female version of the product) in a first main surface (608) of each body strip (602). In this example, the roller mold (604) has a pair of rails (610) inside of it, which form the mold for the projections or recesses of the body bands (602).
    A polyurethane adhesive layer (612) is then applied continuously to a second opposite main surface (614) along the length of each body strip (602) and pressed into place by a pair of rollers (616, 618) to form a base. of building play blocks (603) of the type described in Figures 1 to 8. The body strip (602) may include a shallow flat bottom longitudinal recess in the second main surface (614) as previously described in which the adhesive layer (612) is housed so that an exposed face of the adhesive layer is slightly in front (for example between 0.1 mm and 0.5 mm in front) of the edges of the elongated body strip. The longitudinal recess is preferably formed by the extrusion die so that it is included in the extrusion (600). Before the adhesive layer is applied, the flat bottom longitudinal recess in the second main surface (614) can be prepared or treated with a solvent to prepare it for bonding to the adhesive and to improve bonding of the adhesive. adhesive to the body strip (602) to create a permanent bond. An exposed side of the adhesive layer (612) can be covered with a cover strip pending initial use, and the adhesive layer (612) can be reused in that it can be removed from a surface on which it is stuck and then be stuck on another surface in a reusable way.
    The last step is that the continuously formed body bands (602) are then divided into selected lengths which are generally greater than 200 mm but can be between 200 mm and 3000 mm, and preferably between 500 mm and 2 500 mm.
    Figure 28 is identical to Figure 26 but shows a single wider extrusion (700) which comes out of an extrusion die (701) and is rolled with a roller mold (704) into a body strip (702) which has four projections (706) across its width, as well as an adhesive layer (712) applied to form a base of building play blocks (703) of the type illustrated in Figure 22.
    There are many uses of the building block base according to the invention as will be apparent to those skilled in the art. The base of building blocks can be glued to any suitable surface such as that of a wall, a window, undulating surfaces such as the handles of a bicycle or any three-dimensional profiled surface such as the exterior surface d 'an automobile, a motorcycle, and many other different surfaces. The surface may involve torsion, rotation and bending to an extent permitted by the flexibility of the building block base and the particular arrangement of rigid building blocks with which the building block base must be used. In all cases, the base of building play blocks can be used to create a walkway from one surface to another or even a sinuous undulating structure supported only on its trough sections as shown in Figure 17 or suspended from their crown sections in the case of a height support surface. The configuration of the receiving recesses can vary greatly. With respect to manufacturing, another method of manufacturing the base of building play blocks is by compression molding or injection molding of the relevant material.
