Detailed Description

The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.

Example 1

The following describes embodiments of the building block system provided by the present invention.

According to the invention there is provided a building block system comprising: the front body is a packaging part, all or part of the packaging part forms a buffer structure, and the buffer structure and the first building block are contained in the packaging box; alternatively, the front body does not serve as a cushioning member, but is a separate member and is housed in the packing box together with the first block. The first building block is a rigid particle building block and is provided with a plurality of stable surfaces, and the first building block can stably stand through the stable surfaces, and the stable surfaces can be integral flat surfaces or end surfaces of a plurality of particles which are positioned in the same plane; furthermore, the stabilizing surfaces not only realize the self-standing of the first building block, but also form surface contact with the outer surface or the inner surface of the second building block obtained by the deformation of the front body, so as to be beneficial to the positioning and/or limiting of the second building block and the first building block. The material of first building blocks can be plastics, still can be various timber less preferably, and its surface has the protruding grain that the overlap joint was used and can imbed the recess of protruding grain, has multiple shape and colour, and it is level and smooth for avoiding children to be injured when playing, and the level and smooth second building blocks of also avoiding damaging of first building blocks surface. The front body is a packaging component in the packaging box, such as a side wall structure and a bottom wall structure which play a role in buffering in the packaging box, a partition plate and an independent box body which play a role in separating, and the material is a paperboard material, such as corrugated paper, paperboard and cardboard paper. I.e. the material of the first block is different from the material of the second block.

To this end, it appears that the first block is only a block in a conventional block system, while the former is only a packaging element for receiving a conventional block system, which is an object other than a conventional block system. Indeed, particle building blocks, well known to those skilled in the art, were born in 1932 and invented by Legao. The hard paper packaging box body material is earlier applied to The packaging of The Game of Besieging in Germany chessboard Game in 1817 years; in 1856, high top hat vendors Edward Allen and Edward Healey made a stiffer paper by adding a fluted sheet between two layers of paper, thereby providing stability and warmth to the cap liner, forming corrugated paper. The coexistence of building blocks and corrugated paper has been around 90 years for nearly a century, but in the time of the nearly a century, the building blocks and the packing box and the packing structure thereof still only have the spatial position relationship of packing and packing, which is the thinking and the conventional means of the traditional building block system and the building block packing system. The application breaks through the thinking fixed form, and a novel building block system is formed by adopting non-used hand segments.

In the building block system provided by the invention, the front body is separated from the first building block initially, so that the manual capability of children is cultured to the maximum extent, the first building block is not connected with the front body (namely a packaging part), and the first building block is placed in a containing space formed by the front body (namely the packaging part) and the packaging box, such as a space formed by the side wall, the bottom wall structure and the partition plate and the packaging box, or can be placed in a containing space formed by the front body (namely the packaging part) alone, such as a space in an independent box body.

The front body is provided with folding guide marks 1, the folding guide marks 1 comprise folding lines printed on the front body (namely packaging parts), arrows for indicating folding directions, serial numbers for indicating folding sequences, folding nicks and the like, children can fold the front body (namely packaging parts) into a second building block with a specific structure according to the folding guide marks 1, and the folding guide marks 1 can reduce the difficulty of forming the second building block and reduce the lowest age of the building block system provided by the invention;

the second building blocks are three-dimensional space structures of auto-lock, including stabilizer surface and connection structure, the second building blocks are three-dimensional space structures, for example, the truck box body, still can be arbitrary three-dimensional space structures, such as house, piano, musical instrument etc., its structure auto-lock, can remain stable indeformable under certain external force, the auto-lock is realized through grafting structure on the second building blocks (the truck box body promptly), for making the second building blocks can place at the plane stability, the second building blocks include a stabilizer surface at least, connection structure on the second building blocks can realize being connected of second building blocks and first building blocks, can also realize being connected between a plurality of second building blocks.

In a preferred embodiment, the second block differs from the first block in the function of the lap joint. For example, the connecting structures on the second block that can overlap the first block are distributed in different regions, at least two regions being spaced apart so far that at least one first block of the plurality of first blocks cannot overlap between the two regions, e.g. the minimum spacing between the two regions is greater than the maximum length of the one first block. For example, the second building block has regions which are located on different surfaces, and connecting structures are arranged in the regions, so that the second building block can overlap different first building blocks on different surfaces. From the size perspective, it is more like a first block overlapping a second block, rather than a second block overlapping a first block. From the perspective of the enveloping space, the volume of the enveloping space of a single second block is greater than that of a single first block, and preferably, the volume of the enveloping cuboid space of a single second block is an integer multiple and greater than or equal to two times, for example, three times, four times, ten times, twenty times, thirty times, one hundred times, two hundred times, one thousand times, or two thousand times, of the volume of the enveloping cuboid space of a single first block. In a variation of the above preferred embodiment, the volume of the enveloping cuboid space of the second block may not necessarily be an integer multiple of the enveloping cuboid space of a single first block, for example 6.5 times. In further variations, the envelope space may arrange the dimensional relationship between the first block and the second block in a circular or other geometric shape. The person skilled in the art can understand that the volume of second building blocks is basically obvious or far greater than that of first building blocks, on the one hand, the volume of the whole building block shape after splicing is increased and the material used for first building blocks can be greatly reduced, on the other hand, first building blocks and second building blocks provide different holding feelings for children, and the difference of holding is more obvious when children hold first building blocks and second building blocks respectively with their left and right hands, so as to facilitate the cognitive progress of children. Further preferably, for the same second block and its precursor, the volume of the enveloping cuboid space of the second block is an integer multiple and greater than or equal to two times, for example three times, four times, ten times, twenty times, thirty times, one hundred times, two hundred times, one thousand times, two thousand times, of the volume of the enveloping cuboid space of the precursor.

The second building blocks can be connected with the first building blocks through the connecting structures, the contact mode after the second building blocks are connected with the first building blocks comprises surface contact, the connecting structures on the second building blocks can be circular clamping grooves 4 penetrating through the surfaces of the second building blocks, the second building blocks are connected with the first building blocks in a clamping mode, circular convex particles are inserted into the inner surface of the outer surface of the second building blocks where the circular clamping grooves 4 are located, the surface of the second building blocks penetrates through the surfaces of the circular convex particles until the surfaces of the first building blocks where the circular convex particles are located are attached to the outer surface of the second building blocks where the circular clamping grooves 4 are located, the second building blocks after being connected can rotate around the central rotating shafts of the first circular convex particles, the truck box body can rotate relative to the truck body, the circular convex particles can be pulled out of the circular clamping grooves 4 along the central rotating shafts, and detachable connection of the first building blocks and the second building blocks is achieved. The connecting structure can also be a clamping sleeve, the first building block is integrally inserted into the clamping sleeve, and the first building block is clamped in the clamping sleeve of the second building block through the surface which is not provided with the convex particles by static friction force.

The process of building blocks system transportation and the display sale of putting on the shelf, first building blocks and forebody phase separation, first building blocks and forebody are all accomodate in the packing carton, and forebody itself constitutes packaging structure, and packaging structure and packing carton shape phase-match to together protect first building blocks with the packing carton. Wherein, the first building block is separated from the front body, and has several preferred embodiments. In a first preferred embodiment, when the first block and the front body are received in the packaging box, the surface of the front body is not exposed with the connecting structure capable of overlapping the first block, so that the first block is separated from the front body. In a second preferred embodiment, when the first block and the front body are received in the packaging box, although the front body surface exposes a connecting structure capable of overlapping the first block, the first block does not expose a portion matching the connecting structure, for example, a plurality of first blocks are packaged in a plastic bag. In a third preferred embodiment, the front body is exposed at its surface with a connecting structure capable of overlapping a first block exposed at a portion matching said connecting structure, but separated from each other by being inaccessible due to the first block and the front body being limited or restricted by the packaging space, or the first block is dispensed into the package without overlapping the front body.

When the child has opened the pack, a first plurality of bricks is removed, and one or more precursor bricks are also removed. Preferably, the overlap between the first block and the front body is not possible, but only after the front body has been deformed into the second block by folding.

When the children play with, the lap joint can be realized among a plurality of first building blocks, for example, the lap joint forms a truck head. If a child desires to obtain the truck body, the front body needs to be folded, and the front body may be an unfolded flat plate or a flat rectangular solid. After folding, the front body is transformed into a second building block, for example into a truck box, to which a child can lap the truck head by means of the connecting structure, resulting in a truck.

After children play, restore folding into the forebody with the second building blocks, put into the packing carton with first building blocks and accomodate.

The cardboard material of the front body or the second building block plays a key role in achieving multiple purposes in the whole process from transportation to storage. First, the paperboard material of the precursor plays a role of buffering in transportation. Secondly, during the deformation process, the cardboard material of the precursor enables the second building block to be folded by a weaker child. Thirdly, in the lapping process, the particle lapping among the rigid first building blocks made of plastic needs larger force, so that the building of children is not easy, on one hand, the building cannot be spliced due to the misalignment, and on the other hand, the building cannot be detached due to small force; the paperboard material has certain flexibility and elasticity, and the grooves or the holes of the paperboard material can also enable the plastic particles to slide into the grooves or the holes of the paperboard material by applying pressure under the condition of slight misalignment. Fourth, at the dismantlement in-process, if between first building blocks, children as long as exhaust the full power dismantle can, but to the dismantlement between first building blocks and the second building blocks, if children only exhaust the tearing that the full power probably can cause the second building blocks of cardboard material, therefore children need learn to control strength, and the strength is both can realize dismantling, avoids tearing the second building blocks again. And fifthly, the second building block made of the paperboard can be restored to the front body, and the operation capability of the child in one reverse thinking action is improved.

In the above, the building block system further comprises a packaging box, wherein the front body is a packaging component, and all or part of the packaging component forms a buffer structure; the buffer structure and the first building block are contained in the packing box; in one variation, the front body is a packing box, and the first block is received in the packing box.

In addition, a plurality of second building blocks can be connected with each other, the second building blocks are connected with each other through connecting structures on the second building blocks, the connecting structures are specifically a plug 6 and a slot 3 and a slot 4 which penetrate through the surface of the second building blocks, the plug 6 is inserted into the corresponding slot 3 or the corresponding slot 4 to form plug connection, the plug 6 can be pulled out from the slot 3 or the slot 4 along the insertion direction to realize detachable plug connection, and the second building blocks connected with each other can be separated and restored to be a precursor.

The precursor is provided with a breakable area; the breakable area comprises a reserved part and a separated part; the whole or partial connection of the separating part and the retaining part forms a damaged position, and the separating part can move relative to the retaining part to form an opening after being wholly or partially separated.

The separation portion comprises a pressing tab 2, which may have any geometrical shape, such as a circle, a long and narrow rectangle and a trapezoid on the precursor, i.e. the packaging element, around which the retention portion extends, that is, the precursor material around the pressing sheet 2, the pressing sheet 2 and the holding portion are flexibly connected by the pressing groove 5, the pressing sheet 2 and the precursor material around the pressing sheet are connected by the pressing groove 5 formed by the scoring, the pressing groove 5 is damaged after a certain external force is applied, the external force is small so that a child can easily apply the external force to the pressing groove 5 and damage the pressing groove, the pressing sheet 2 can move relative to the reserved part to form the slot 3 or the clamping groove 4 after being pressed, after the pressing sheet 2 is pressed by the child, the pressing groove 5 is broken, the connection part of the pressing sheet 2 and the precursor material around the pressing sheet is partially or completely broken, and the pressing sheet moves relative to the precursor material around the pressing sheet to form the slot 3 or the slot 4.

Example 2

The following description is directed to preferred embodiments of the building block system provided by the present invention.

Fig. 1-41 are schematic views of a building block system provided by the present invention.

According to the invention there is provided a building block system comprising: the front bodies are arranged in the packaging box of the building blocks in a packaging part mode, are positioned on the periphery and the bottom surface of the packaging box and play a role in buffering, the first building blocks are arranged in the containing space defined by the packaging parts, the packaging parts protect the first building blocks from being extruded and damaged by external force in the transportation process, and the front bodies, namely the packaging parts, are made of corrugated paper; alternatively, the precursor bodies are not cushioning but are merely separate components and are accommodated in the package together with the first building blocks, and the material of these precursor bodies is corrugated paper.

The first building block is a rigid particle building block and is provided with a plurality of stable surfaces, and the first building block can stably stand through the stable surfaces, and the stable surfaces can be integral flat surfaces or end surfaces of a plurality of particles which are positioned in the same plane; furthermore, the stabilizing surfaces not only realize the self-standing of the first building block, but also form surface contact with the outer surface or the inner surface of the second building block obtained by the deformation of the front body, so as to be beneficial to the positioning and/or limiting of the second building block and the first building block. The material of first building blocks is plastics, and its surface has the protruding grain that the overlap joint was used and can imbed the recess of protruding grain, has multiple shape and colour, and it is level and smooth for avoiding children's injured external surface when playing, and the level and smooth second building blocks of also avoiding damaging of first building blocks external surface.

The packaging unit is removed by a child after opening the package, and fig. 1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34 show the initial condition of the packaging units after removal from the package of the building blocks, in which the packaging units are not folded and assembled. As shown in fig. 1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34, the surfaces of these packaging elements are provided with fold guide markings 1, in particular fold lines printed on the surfaces of the packaging elements and pre-embossed fold scores, which guide the child in folding the packaging elements in a certain manner, fig. 2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35, which show the folding of the packaging elements by the child according to the fold guide markings 1, while the fold scores also reduce the force required to fold the packaging elements, which reduces the difficulty of the child in folding the packaging elements to form a second building block and reduces the minimum age of the building block system provided by the invention.

Fig. 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36 show a state in which each packaging element has been folded into a plurality of second blocks, but has not yet been spliced, each of the second blocks is of a three-dimensional structure and includes a stabilizing surface and a connecting structure, the second blocks can be spliced to form a toy truck box body, the second blocks are self-locked by folding and splicing themselves and can be kept stable and not deformed under a certain external force, which ensures that the folded second blocks cannot be opened and restored to a state before folding when being grabbed and spliced by children, in order to enable each second block to be stably placed on a plane when not being spliced, each second block includes at least one flat stabilizing surface, which also ensures to some extent that the truck box body obtained by splicing the second blocks has a stabilizing surface and can be stably placed on a plane, and the connecting structure on the second blocks can realize connection of the second blocks with the first block, and the connection among a plurality of second building blocks can be realized.

The second block is functionally different from the first block in the lap joint. As shown in fig. 12, the slots 3 on the floor 10 are distributed in different areas on the floor 10, and the slots 3 at the front end and the rear end of the floor 10 are far apart, so that at least one first block and one second block connected with the first block cannot be overlapped between the two areas, as shown in fig. 37, the two first blocks are respectively inserted into the slots 3 at different areas on the floor 10, and as shown in fig. 38, the front block 13 and the rear block 11 are respectively inserted into the slots 3 at the front end and the rear end on the floor 10. As shown in fig. 12, the upper surface and the lower surface of the floor 10 are provided with the insertion grooves 3, so that the second block can be respectively overlapped with the first block and the second block on different surfaces. From a size perspective, it is more likely that the first block will overlap the floor panel 10 than the floor panel 10 will overlap the first block, as shown in FIG. 37. From the perspective of the envelope space, compare the size of floor 10 in fig. 37 with first building blocks, the volume of the envelope space of a single floor 10 will be obviously greater than the envelope space of a single first building block, on the one hand, this makes the volume increase of whole building block molding and the material of first building block can reduce by a wide margin after the concatenation, and on the other hand, first building block and second building block provide different sense of holding to children, and this kind of difference sense of holding is more obvious when children's left and right hands hold first building block and second building block respectively, so as to be favorable to children's cognitive progress.

The second building blocks are connected with the first building blocks through the connecting structures, and the contact mode of the second building blocks after the second building blocks are connected with the first building blocks comprises surface contact. Specifically, as shown in fig. 39, the truck body is connected to the truck head by clamping the circular protruding grains on the surface of the first building block on the truck head with the circular clamping grooves 4 on the front end of the lower surface of the floor 10, as shown in fig. 40, the circular protruding grains on the first building block are inserted inwards from the lower surface of the floor 10 where the circular clamping grooves 4 are located, and penetrate through the lower surface of the floor 10 until the surface of the first building block where the circular protruding grains are located is attached to the lower surface of the floor 10 where the circular clamping grooves 4 are located, the clamped floor 10 can rotate around the central rotating shaft of the circular protruding grains of the first building block, so that the truck body rotates relative to the truck head, and the circular protruding grains can be pulled out from the circular clamping grooves 4 along the center of the rotating shaft, so that the truck head is detachably connected to the truck body. In addition, the first building block is connected with other second building blocks through the second building block with the connecting function. Specifically, as shown in fig. 41, on the one hand, the insertion of the elongated slot 3 and the rib restricts the relative position of the first connecting element 15 and the first building block, and on the other hand, the diameter of the circular protrusion on the first building block is larger than that of the circular slot 4, and the insertion of the circular protrusion slightly expands the circular slot 4, so that the first connecting element 15 slightly expands the circular slot 4. Subsequently, as shown in fig. 37, the plug 6 of the first connecting element 15 is plugged into the socket 3 of the floor panel 10, and the first building block is connected to the floor panel 10 via the first connecting element 15.

A plurality of second building blocks can be connected with each other, and the connection of the second building blocks is realized through a connecting structure on the second building blocks. Specifically, four plugs 6 are arranged at the upper part of the axle box 8 shown in fig. 6, and the plugs 6 are inserted into the corresponding slots 3 on the lower surface of the floor 10 to realize the connection between the axle box 8 and the floor 10; the lower part of the display stand 18 shown in fig. 36 is provided with two plugs 6, and the plugs 6 are inserted into corresponding slots 3 on the upper surface of the floor 10 to connect the display stand 18 with the floor 10; in addition, the connection of the first connecting piece 15, the second connecting piece 16 and the third connecting piece 17 with the rear mud guard 7, the front mud guard 9, the floor 10, the rear box block 11, the side box blocks 12, the front box block 13 and the box cover 14 is realized in a plug-in mode of the plug 6 and the slot 3. The second connecting piece 16 is a second building block, and realizes the connection between two second building blocks which do not move relatively, including the connection between the front mud guard 9 and the floor 10, the rear mud guard 7 and the floor 10, the front box block 13 and the floor 10, the rear box block 11 and the floor 10, the side box block 12 and the floor 10, the front box block 13 and the side box block 12, and the rear box block 11 and the side box block 12, two plugs 6 of the second connecting piece 16 are respectively inserted into the slots 3 on the two second building blocks connected with the second connecting piece, and the two second building blocks are connected together through the second connecting piece 16.
