[0001] Parent case information

[0002] This application is a divisional application of Chinese Patent Application No. 202080009688.3, titled “Flexible construction units, kits, and methods for constructing structures.”

[0003] Cross-reference to Related Applications

[0004] This application claims priority to U.S. Application Serial No. 16 / 296,543, filed March 8, 2019. The entire disclosure of the above application is incorporated herein by reference. TECHNICAL FIELD

[0005] The present application relates to systems and methods for constructing structures, and more particularly to construction units formed from flexible sheet material. BACKGROUND

[0006] Children are often attracted to toys that can be assembled. The act of creation helps children develop spatial awareness and can provide hours of entertainment.

[0007] Various toys that require assembly are known in the art. However, many known toy construction pieces are rigid and inflexible, and are often difficult to connect and disconnect, particularly for young children.

[0008] Typically, the known toys are composed of many pieces that can be connected together, for example, by using friction fit fasteners, glue, or magnets. Certain toys are described in U.S. Patent Application Serial No. 2016 / 0074766 to So Young Choi and U.S. Patent No. 8,850,683 to Christopher Haughey et al., each of which teaches a block toy having magnets embedded therein such that when the blocks are placed in close proximity to one another, the blocks easily combine through magnetism. Another known toy is described in U.S. Patent No. 9,914,067 to Sufer et al., which includes a flexible construction segment having rib portions and embedded magnets.

[0009] There is an ongoing need for a construction unit that can be assembled in various ways to easily form three-dimensional shapes and structures. Desirably, the pieces of the construction unit are flexible and easily connect and disconnect. Most desirably, the construction unit is entertaining for children and adults and can be used as a toy. SUMMARY

[0010] According to the present application, it is surprisingly found that a building unit can be assembled in various ways to easily form three-dimensional shapes and structures, and the building unit has components that are flexible and easily connected and disconnected, and the building unit is entertaining for children and adults and can be used as a toy.

[0011] In one embodiment, the building unit can have a body. The body can be formed from at least one piece of flexible material. The body can have a first side and a second side. The building unit can have a plurality of magnetic connectors attached to the body.

[0012] In another embodiment, a kit for building a structure can have a plurality of building units. The plurality of building units can include a plurality of shapes. The kit can further include an active unit and a control unit configured to be in electronic communication with each other. The active unit and the control unit can be placed in electronic communication via a flexible link.

[0013] In another embodiment, a method of manufacturing a structure includes a first step of providing a plurality of building units. The method includes a second step of connecting at least one of the magnetic connectors of a first one of the building units with another one of the magnetic connectors of the first one of the building units and at least one of the magnetic connectors of a second one of the building units. A structure is thereby formed.

[0014] In an exemplary embodiment, the building unit is a toy. The toy can include a flexible sheet having a plurality of magnets embedded within the flexible material of the sheet. The magnets can be on a perimeter of the flexible material.

[0015] The magnets of the first flexible sheet are removably adhered to the magnets of the second flexible sheet. In other words, the connection of the first and second sheets need not be permanent, and the first and second flexible sheets can instead be connected by the magnets in a first arrangement, and then separated and reassembled into a second arrangement as desired. The first and second sheets can be configured to form a three-dimensional structure.

[0016] The toy can include at least one module removably adhered to the flexible sheet by the magnets, or to the magnets of a three-dimensional structure formed from one or more flexible sheets.

[0017] In particular, the present application relates to embedding magnets into paper or any other flexible sheet, in order to build a three-dimensional structure. While there can be other common ways of connecting the sheets together, such as stapling, gluing, masking tape, etc., none of the said ways have an easy way of disassembling.

[0018] For some purposes, it is essential to have an easy way to connect and disconnect the sheets. When manufacturing three-dimensional shapes with multiple sheets, there is no easy solution to connect the sheets to each other and then disconnect them. The present application seeks to provide a solution to the problem by providing magnets embedded in the flexible sheets that allow the sheets to be easily connected to other sheets and then easily disconnected from each other only. Magnets embedded in flexible sheets allow sheets to be connected to themselves to form three-dimensional shapes. One sheet can actually form more than one three-dimensional shape as needed. In addition, a single sheet can be connected to other sheets in various ways to form three-dimensional shapes and structures.

[0019] Magnets can be embedded within the sheets using special devices or attached to the sheets in a way that the magnets are permanently fixed to the sheets. More than one magnet can be embedded within the same sheet. Thus, the magnets are able to attract each other and form three-dimensional shapes in the sheets. In addition, sheets can be connected to other sheets in various ways to form three-dimensional structures.

[0020] As a technical supplement to the sheets, there are various magnet modules (for example, electronic modules also containing a power source such as a battery) that each function once it is magnetized to the embedded magnets on the sheets. The modules can be plastic boxes containing multiple electronic components and having input sensors (for example, proximity / light sensors, orientation sensors, sound sensors) or output components with functional capabilities (for example, sound, light, and / or motion). The modules can be connected to the Internet cloud and / or mobile remote devices, for example, by using wireless transmission (for example, Bluetooth). The modules can also be activated from a removal device (for example, a smartphone (for example, iPhone) or a tablet computer (for example, iPad)). Other suitable types of sensors and electronic components can also be used as needed. Once this module is assembled with the three-dimensional structure, it gives the three-dimensional structure additional technical features, such as movement of the three-dimensional sheet structure or a light that shines through the sheets, where the sheets are translucent or transparent.

[0021] It should also be understood that the sheets can have a pattern of multiple holes or a single hole (for example, for light to pass through, or to be used as an additional connector). The holes can be used for light distribution in addition to or separately from the translucency or transparency of the sheets, as needed.

[0022] The magnets can be placed on the corners of the flexible sheets. In particular, the magnets can be disc-shaped magnets. Their size will be chosen according to the kind of sheet used. If a sheet is used that is less flexible (for example, thick polypropylene), larger magnets can be needed. If a softer sheet is used (for example, ordinary paper), smaller magnets can be needed.

[0023] The magnets are embedded into the sheet in a variety of ways chosen by the manufacturer. They can be glued, laminated, contained in a plastic cavity, laminated between two sheets, or in any other way, as long as the magnets are embedded onto the sheet in a way that makes the magnets immovably fixed onto the sheet.

[0024] Two sheets with embedded magnets can attract each other. Another option is to magnetize the sheet itself to form a three-dimensional shape, such as a cylinder. Two or more sheets can be attracted to each other by the magnets to form a three-dimensional structure, such as a tower. By connecting several sheets together in various ways, one can construct many different objects, such as animals, robots, vehicles, etc. One example of such a structure is a fortress.

[0025] As a non-limiting example, a dynamic magnetic flexible sheet is created by adding a magnetic module of, for example, 1 cubic centimeter in size (or any size up to 1000 cubic centimeters) to any construction. One example of a suitable module is disclosed in U.S. Patent Application Publication No. 2015 / 0325949 to Zhengpeng Wei, the entire disclosure of which is incorporated herein by reference. Other suitable magnetic modules can also be selected by those skilled in the art as desired.

[0026] When a magnetic module is connected to a magnet and thus turns itself "on", it converts the construction into a dynamic construction. A dynamic construction can include movement such as rotation of a blade like a windmill or a rotating moving device. In alternative embodiments, the magnetic module can be used as a connection point rather than a switch. The module can be connected to the internet, the cloud, and / or mobile remote devices, or can be networked in other ways as understood by those of ordinary skill in the art.

[0027] Although described primarily herein as a "toy", it should be understood that the novel constructions of the present application can also have other applications, including decorative and functional constructions, as non-limiting examples. All such other uses of the novel constructions are contemplated and considered to be within the scope of the present application.

[0028] In particular embodiments, a toy can include flexible sheets that can form various shapes and structures. The flexible sheets can be folded in such a way to create a three-dimensional structure.

[0029] The flexible sheets can be removably adhered to themselves or other sheets using magnets. The flexible sheets can be made of paper, plastic, metal, rubber, silicone, or any other material selected by those skilled in the art. Furthermore, the magnets can be neodymium iron boron (NdFeB), samarium cobalt (SmCo), alnico, ceramic, ferrite, or any other type of magnet selected by those skilled in the art. For example, the magnets can be disc-shaped magnets.

[0030] While the flexible sheet is generally rectangular, the flexible sheet can be various shapes as desired, including but not limited to circular, square, triangular, hexagonal, or any type of polygon.

[0031] The magnets are primarily shown on the outer perimeter of the sheet. However, it should be appreciated that a person of skill in the art can place the magnets in any suitable location or orientation on the flexible sheet.

[0032] Additionally, while the use of magnets can be preferred, it should be appreciated that the sheet can also be removably adhered in other ways, including snaps, buttons, latches, or any other suitable mechanism selected by a person of skill in the art, and such fasteners are also considered within the scope of the present application.

[0033] Special means can also be used to embed the magnets into the flexible sheet, thereby securing the magnets to the flexible sheet. More than one magnet can be attached to the same sheet. In other examples, the flexible sheet can be formed by layering two sheets together and thereby locking the magnets between the layers forming the sheet. Thus, one magnet can be adhered to an opposing magnet on the same sheet, forming a three-dimensional shape. The magnets can be secured to the sheet in various ways, including but not limited to glue, lamination, heat fixation, or any other mechanism selected by a person of skill in the art. Furthermore, multiple sheets with embedded magnets can be removably adhered to each other.

[0034] The magnets can be placed on the perimeter of the flexible sheet. Additionally, the size of the magnets depends on the type of sheet. For example, thicker sheets can require larger or stronger magnets, while more flexible sheets can require smaller or less powerful magnets.

[0035] Two or more sheets can be magnetized to each other to form a three-dimensional structure, such as a tower. By adhering the magnets disposed in multiple sheets together in various ways, many different objects can be constructed, such as animals, robots, vehicles, or any other structure selected by a person of skill. As an example, there is a fort composed of sheets that are removably using magnets.

[0036] Additionally, a user can attach a module to the flexible sheet. The module has a magnet configured to adhere to the magnet attached to the flexible sheet. In certain embodiments, the magnet attached to the module can be 1 cubic centimeter, and up to 1000 cubic centimeters.

[0037] The module can produce sound, light, or motion. For example, the module can include at least one of a speaker, an LED light, and a motor. The module can also have a power source, such as a battery. The module can also include a microprocessor and memory and be configured to perform certain programmable actions.

[0038] The modules can also be attached to the sheet in a three-dimensional structure. The three-dimensional structure together with the modules can provide movement of the three-dimensional sheet structure.

[0039] Furthermore, the modules can have transceivers and be configured to wirelessly communicate with various user devices such as personal computers or mobile devices. The modules can use Bluetooth, WIFI or other appropriate form of wireless communication as desired. Furthermore, there can be multiple modules configured to work together. The multiple modules can be attached to a sheet to form a robot, a drone or any other toy as selected by the skilled person. For example the modules can be arms, legs and the head of a robot, wheels wirelessly controlled to form a remote control car or arms and legs forming a dancing toy doll. In another example, a module with a rotating arm connects to a fort.

[0040] The modules can also "turn on" only when adhered to another magnet. When the module is magnetized, it activates, causes the module to activate an input sensor or light up, produces a sound or causes movement.

[0041] Advantageously, the toys as described above can be assembled in various ways to easily form three-dimensional shapes and structures. It will be appreciated that the toys described above have components in the form of flexible sheets that are flexible and easily connected and disconnected in operation.

[0078] The following description is exemplary in nature only and is not intended to limit this application, application, or use. It should also be understood that in all the figures, corresponding reference numerals denote the same or corresponding parts and features. Regarding the disclosed method, the order of the presented steps is exemplary in nature and therefore not necessary or critical unless otherwise disclosed.

[0079] like Figures 1-21 As shown, the construction unit 100 may have a body 102. The body 102 may be formed of a flexible material. The body 102 may have a first side 104 and a second side 106. The construction unit 100 may have a plurality of magnetic connectors 108 attached to the body 102.

[0080] As used herein, the term "body" is defined as including any body having a width and length substantially greater than its thickness. Body 102 may include one or more layers or sheets of flexible material, as further described herein. It should be understood that body 102 will allow magnetic connector 108 to be embedded therein or attached thereto, or facilitate the placement of magnetic connector 108 between two or more layers or sheets of body 102, also as further described herein. Unless otherwise disclosed, the term "body" should not be construed as implying any particular shape or overall size, and is intended to include any and all possible shapes and sizes.

[0081] The flexible material of this application is flexible yet elastic, such that it returns to its initial shape without significant wrinkling or tearing after deformation or bending. It should be understood that in some embodiments, the flexible material may also retain its shape after bending or deformation. The flexible material is also water-resistant and does not significantly degrade upon exposure to water. The flexible material is also resistant to degradation upon exposure to oil. In some embodiments, the flexible material forming the body 102 may be selected from the group consisting of paper, synthetic paper, leather, synthetic leather, elastomers, plastics, rubber, metals, fabrics, composite materials, and combinations thereof.

[0082] In particular embodiments, the flexible material can be a waterproof synthetic paper. For example, the flexible material can be a polyester or polyolefin based synthetic paper. As a non-limiting example, the polyester or polyolefin based synthetic paper can have a thickness between about 3.7 mils and about 13.7 mils, and a weight between about 125 gsm and about 510 gsm. In another example, the polyester or polyolefin based synthetic paper can also have a melting point between about 285 °F and about 450 °F. Advantageously, the construction unit 102 made of the polyester or polyolefin based synthetic paper provides a lightweight and waterproof construction unit 102 that can be reused without undesirably tearing or creasing. Although the polyester or polyolefin based synthetic paper has been found to be particularly suitable for the body 102, it should be understood that any other suitable material can be selected by those skilled in the art as desired.

[0083] The body 102 of the present application can also have dimensions that facilitate manual deformation or bending of the body 102 in operation. In certain embodiments, the flexible material of the body 102 can have a thickness between about 0.1 millimeter and about 25 millimeters. In more particular embodiments, the flexible material of the body 102 can have a thickness between about 0.1 millimeter and about 5 millimeters. In most particular embodiments, the flexible material of the body 102 can have a thickness between about 0.1 millimeter and about 1.0 millimeter. In particular embodiments, the thickness of the body 102 can be about 0.3 millimeters. Other suitable thicknesses for the body 102 can also be selected by those of ordinary skill in the art within the scope of the present application.

[0084] As shown in FIGS. 1-3, the body 102 can have a central hub 110. The central hub 110 can have a plurality of arms 112 disposed thereon. Each of the plurality of arms 112 can radiate outwardly from the central hub 110 and have a free end 114. In certain embodiments, as shown in FIGS. 1-3, the body 102 can have a substantially X-shape, wherein four arms 112 are disposed on the central hub 110. Although the body 102 having an X-shape is shown and described herein as one particular example, it should be understood that any other suitable shape for the body 102 is contemplated by the present application. Figures 1-5 Figures 1-5 As shown in FIGS. 1-3, the body 102 can have a central hub 110. The central hub 110 can have a plurality of arms 112 disposed thereon. Each of the plurality of arms 112 can radiate outwardly from the central hub 110 and have a free end 114. In certain embodiments, as shown in FIGS. 1-3, the body 102 can have a substantially X-shape, wherein four arms 112 are disposed on the central hub 110. Although the body 102 having an X-shape is shown and described herein as one particular example, it should be understood that any other suitable shape for the body 102 is contemplated by the present application.

[0085] ​Magnetic connectors 108 may be disposed on the body 102. For example, magnetic connector 108 may be disposed on the arm 112 of the body. For example, magnetic connector 108 may be disposed adjacent to the free end 114 of the arm 112. In some cases, magnetic connector 108 may be disposed at the central hub 110. In another example, magnetic connectors 108 may be spaced apart from each other across a region of the body 102. In particular, it has been found that magnetic connectors 108 should be disposed on the body 102 at a distance of at least about 60 mm to 70 mm to facilitate the use of the construction unit 100. Other suitable positions and arrangements for magnetic connectors 108 may also be adopted.

[0086] like Figures 6-12 As shown, each magnetic connector 108 may have a first portion 116, a second portion 118, and a magnet 120. The first portion 116 may be positioned adjacent to a first side 104 of the body 102. The second portion 118 may be positioned adjacent to a second side 106 of the body 102. The magnet 120 may be positioned between the first portion 116 and the second portion 118. The first portion 116 and the second portion 118 thereby secure the magnet 120 to the body 102.

[0087] like Figures 1-4 As shown in Figures 6-7 and 10-12, the magnetic connector 108 of this application may have a generally hexagonal shape. It should be understood that, in operation, the hexagonal shape can prevent unintended rotation of various components that may be connected to the magnetic connector 108. The hexagonal shape may also be provided with rounded corners, which can prevent unintentional jamming or cutting of the body 102 if the body 102 has been deformed or bent as further described herein. However, by way of non-limiting example, the magnetic connector 108 may be any other suitable shape, including circular and square.

[0088] As a non-limiting example, the magnetic connector 108 can be manufactured from a lightweight plastic material such as acrylonitrile butadiene styrene (ABS) via a molding process such as injection molding. It should be understood that the magnetic connector 108 can be formed from any other suitable material, including other thermoplastic materials such as polyethylene. Any suitable process for forming the magnetic connector 108 may also be employed as needed.

[0089] like Figures 6-12As shown, the first portion 116 of the magnetic connector 108 can have an outer surface 122 and an inner surface 124. The first portion 116 can have a central aperture 126 formed therethrough. The central aperture 126 can extend from the outer surface 122 to the inner surface 124. The central aperture 126 can be configured to house the magnet 120. In certain embodiments, the central aperture 126 can be formed in the inner surface 124 but not all the way through to the outer surface 122 of the first portion 116. In other words, the central aperture 126 can be provided in the form of a closed recess that only opens to the inner surface 124 and not to the outer surface 122.

[0090] As Figure 7 and 11 As shown in FIG. 12, the second portion 118 of the magnetic connector 108 can have an outer surface 128 and an inner surface 130. The second portion 118 can have a central aperture 132 formed therethrough from the outer surface 128 to the inner surface 130. The central aperture 132 can also be configured to house the magnet 120. In certain embodiments, the central aperture 132 can be formed in the inner surface 130 but not all the way through the second portion 118 to the outer surface 128. Like the first portion 116 of the magnetic connector 108, the central aperture 132 can be provided in the form of a closed recess that only opens to the inner surface 130 and not to the outer surface 128.

[0091] As Figure 11 and 12 As further shown, the second portion 118 can have a flange 133 formed in its inner surface 130. The flange can bound the central aperture 132. The second portion 118 can have an annular ring 135. The annular ring 135 can be formed on its outer surface 128. The annular ring can surround the central aperture 132.

[0092] Referring now to Figure 10 The first portion 116 of each magnetic connector 108 has at least one recessed member 134. The recessed member 134 can be a hole disposed through the first portion 116 from the outer surface 122 to the inner surface 124. It should also be understood that the recessed member 134 can only open on the inner surface 124 and can be closed on the outer surface 122 (not shown). More specifically, the first portion 116 can have a plurality of recessed members 134 disposed about the central aperture 126 of the first portion 116.

[0093] In the most specific example also shown in Figure 10 The recessed member 134 can include four holes formed through the first portion 116 from the outer surface 122 to the inner surface 124. The four holes can be substantially evenly spaced about the central aperture 126 of the first portion 116.

[0094] Referring to Figure 11The second portion 118 of each magnetic connector 108 can have at least one male component 136. The male component 136 of the second portion 118 can correspond in size and shape to the female component 134 of the first portion 116. The male component 136 can protrude outwardly from the inner surface 130 of the second portion 118. The male component 136 can be formed separately and then attached to the inner surface 130, or the male component 136 can be formed in conjunction with the remainder of the second portion 118 on the inner surface 130 as desired.

[0095] In one still more particular example shown in Figure 11 The male component 136 can include four pegs in the most particular example shown in FIG. 6. The pegs are formed on the inner surface 130 of the second portion 118. The male component 136 can also be spaced substantially evenly around the inner surface 130.

[0096] It will be appreciated that the male component 136 can be adapted to be received by the female component 134 when the magnetic connector 108 is assembled. For example, the male component 136 can be friction fit or press fit into the female component 134 such that the first portion 116 and the second portion 118 are held together. In other examples, the male component 136 and the female component 134 can not be press fit, but can instead be used to align the first portion 116 and the second portion 118 for an additional connection process, as further described herein.

[0097] Advantageously, the male and female components 134, 136 provide a secure coupling of the first portion 116 and the second portion 118, and can prevent adverse separation of the first portion 116 and the second portion 118 during use. It will be appreciated that a person of ordinary skill in the art can select any suitable size and shape of the male and female components 134, 136, and any suitable placement or configuration of the male and female components 134, 136 on the first portion 116 and the second portion 118 as desired.

[0098] With continued reference to Figure 11 The second portion 118 of the magnetic connector 108 can have at least one weld bridge 138. The weld bridge 138 can be provided in addition to the male component 136 described above, and the weld bridge 138 can be formed separately and then added to the inner surface 130, or in conjunction with the remainder of the second portion 118. For example, as shown in Figure 9 The weld bridge 138 can be defined by an elongated rib having an uppermost peak configured to be welded to the inner surface 124 of the first portion 116. In particular, as shown in Figure 11As shown, at least one welding bridge 138 may include four welding bridges 138 spaced apart from each other and arranged around the central hole 132 of the second portion 118. Those skilled in the art may also choose any other suitable size, shape, number, and arrangement for the at least one welding bridge 138 as needed.

[0099] like Figure 9 As shown, at least one welding bridge 138 can connect the inner surface 130 of the second portion 118 to the inner surface 124 of the first portion 116. It should be understood that at least one welding bridge 138 is configured to pass through the body 102 to securely attach the magnetic connector 108 to the body 102. In a specific example, at least one welding bridge 138 can be ultrasonically welded to the inner surface 124 of the first portion 116 to connect the first portion 116 and the second portion 118. It should be understood that those skilled in the art can also choose any suitable means for connecting the first portion 116 and the second portion 118 within the scope of this application.

[0100] Now for reference Figure 13 The body 102 may have a plurality of pre-formed holes 140 formed therethrough. At least one of the pre-formed holes 140 may accommodate one of the magnetic connectors 108. In some embodiments, the pre-formed holes 140 may be formed in the central hub 110, a plurality of arms 112, the free ends 114 of the arms 112, or any combination thereof. Those skilled in the art can select any suitable location for the plurality of pre-formed holes 140 as needed.

[0101] The size and shape of the pre-drilled holes 140 can be selected based on the structure of the magnetic connector 108 with which they are to be used. Specifically, the plurality of pre-drilled holes 140 may include magnet holes 142, solder bridge holes 144, and protrusion holes 146. Magnet holes 142 can accommodate magnets 120. Solder bridge holes 144 can accommodate solder bridges 138 of the second portion 118. Protrusion holes 146 can accommodate protrusions 136. Other suitable types, including pre-drilled holes 140 of different sizes and shapes, may also be used.

[0102] In one most specific embodiment, the weld bridge hole 144 and the protrusion hole 146 may be spaced apart from each other and generally surround the magnet hole 142. The weld bridge hole 144 and the protrusion hole 146 may be arranged alternately and substantially uniformly around the magnet hole 142. Other suitable arrangements may also be used.

[0103] As a non-limiting example, the device 140 used to create the preformed hole can include a die cutting process. It should be appreciated that forming the preformed hole 140 in the flexible material by die cutting can allow the second portion 118 to pass through the body 102 without requiring an uncontrolled tear or perforation of the body 102 by the male component 136 and the weld bridge 138 of the second portion 118 at assembly. It should also be appreciated that the use of the preformed hole 140 thus facilitates a superior life of the construction unit 100 with repeated deformation and bending over time due to the absence of uncontrolled tears or perforations that would otherwise be present in the body 102. Other suitable devices for forming the preformed hole 140 without excessive tearing of the flexible material can also be used as desired.

[0104] Referring again to Figure 6 and Figure 10 , the first portion 116 has a plurality of first ratchet teeth 148. The first ratchet teeth 148 can be disposed on the outer surface 122 about the central hole 126 of the first portion 116. In certain embodiments, the first portion 116 can have an annular groove 150 formed in the outer surface 122 about the central hole 126 of the first portion 116. The first ratchet teeth 148 can be disposed on the outer surface 122 within the annular groove 150.

[0105] In certain examples, the first ratchet teeth 148 each have a peak 152. The peak 152 of the first ratchet teeth 148 can be spaced apart from the plane on which the remainder of the outer surface 122 is disposed. For example, the peak 152 can be recessed in the annular groove 150 such that each peak 152 is disposed below the entirety of the outer surface 122.

[0106] As shown in Figure 7 and 12 , the second portion 118 also has a plurality of second ratchet teeth 154. The second ratchet teeth 154 can be disposed on the outer surface 128 and arranged in an annular ring about the hole 132 of the second portion 118. The second ratchet teeth 154 can protrude outwardly from the outer surface of the second portion.

[0107] In operation, the first ratchet teeth 148 of the first one of the magnetic connectors 108 can be configured to cooperate with the second ratchet teeth 154 of the second one of the magnetic connectors 108. Advantageously, the cooperation of the first ratchet teeth 148 and the second ratchet teeth 154 prevents undesirable rotation of the magnetically connected construction unit 100. Furthermore, the cooperation of the first ratchet teeth 148 and the second ratchet teeth 154 provides a desirable tactile feel when the magnetic connectors 108 are turned relative to one another when magnetically connected.

[0108] It should also be understood that the aforementioned recess of the peak 152 of the first ratchet tooth 148 in the annular groove 150 of the first portion 116, together with the outward protrusion of the second ratchet tooth 154 of the second portion 118, can also provide a more robust or stable connection between the first magnetic connector 108 and the second magnetic connector 108 in operation.

[0109] As described above, each magnetic connector 108 includes a magnet 120 adapted to induce a magnetic connection with adjacent magnetic connectors 108. The magnet 120 has sufficient magnetic field strength or field to allow selective magnetic connection of the magnetic connectors 108 to be manually set adjacent to each other, while also allowing a user, such as a child, to selectively and manually disconnect the magnetic connectors 108. Specifically, the magnet 120 may be a rare-earth type magnet or a magnetic alloy. As a non-limiting example, the magnet 120 may include neodymium iron boron (NdFeB), samarium cobalt (SmCo), nickel-cobalt alloys, ceramics, ferrites, or combinations thereof. Any other suitable type of magnet 120 may be chosen by those skilled in the art.

[0110] In some examples, such as Figures 1-5 and Figure 20 As shown, the magnet 120 is immovably fixed to the body 102. For example, immovable fixing of the magnet 120 can be provided by friction fit or press fit. The magnet 120 can also be fixed to the magnetic connector 108 using adhesive. However, in Figures 21-22 In other examples shown, the magnet 120 may also be freely rotatable within the magnetic connector 108. It should be understood that a freely rotatable magnet 120 allows a user to connect adjacent magnetic connectors 108 without regard to the position of the magnetic poles, which will freely rotate to the correct orientation. The freely rotatable magnet 120 may be loosely disposed within, for example, a plastic or metal housing 153 encapsulated within the magnetic connector 108 or body 102. Other suitable means may also be employed to attach the magnet 120 to the magnetic connector 108 or body 102 in either a non-removable or removable manner.

[0111] like Figures 8-9 As shown, magnet 120 has a first segment 156 and a second segment 158. The first segment 156 may have a first width (W1). The second segment 158 ​​may have a second width (W2). The first width (W1) is greater than the second width (W2). The first segment 156 of magnet 120 may abut or abut against or adjacent to the flange 133 of the second portion 118 of magnetic connector 108. The second segment 158 ​​of magnet 120 may be received by the central hole 132 of the second portion 158 of magnetic connector 108.

[0112] In some embodiments, the same applies. Figures 8-9As shown, the magnets 120 can be spaced a distance (Dl) from the outer surface 122 of the first portion 116 and define a recess 159 with the surrounding area of the first portion 116. In operation, the annular ring 135 of the first one of the magnetic connectors 108 can be configured to rest on the outer surface 122 and be received by the recess 159 of the second one of the magnetic connectors 108. In certain examples, the recess 159 can be shaped to frictionally or press fit with the annular ring 135. Advantageously, the mating of the annular ring 135 and the recess 159 of the outer surface 122 can provide a more secure or stable connection of the first and second one of the magnetic connectors 108 in operation.

[0113] According to Figures 19-20 As shown in the optional embodiment, the body 102 can include a plurality of sheets 103, 105. The plurality of sheets 103, 105 can include a first sheet 103 and a second sheet 105. The magnetic connectors 108 can be disposed between the first sheet 103 of flexible material and the second sheet 105 of magnetic material. One of the magnetic connectors 108 can be connected to another one of the magnetic connectors 108 disposed within the same body 102. The magnetic connectors 108 of one body 102 can also be connected to magnetic connectors 108 disposed on a separate and distinct body 102. It should be appreciated that the construction unit 100 can thereby be connected to itself, or to other construction units. The other construction units can be of any size or shape. The size, shape, number, and arrangement of the magnetic connectors 108 between the first and second sheets 103, 105 can also be selected by one of skill in the art as desired.

[0114] In another optional embodiment, as Figures 23-24 shown, the magnets 120 can be disposed in a rotating magnet housing 151. The magnets 120 can extend outwardly beyond the rotating magnet housing 151 so as to connect with other magnets presented by an adjacent magnet housing 151. For example, in operation, the magnets 120 of a first construction unit 100 can directly connect to the magnets 120 of the magnets 120 of another construction unit 100.

[0115] The rotating magnet housing 151 can have a pair of shafts 155. Each shaft of the pair of shafts 155 can be disposed on one end of the rotating magnet housing 151. Each of the pair of shafts 155 can be rotatably coupled to the magnetic connector 108, such as by rotatably disposing the shaft 155 within a corresponding hole formed in the magnetic connector 108, such that the magnet housing 151 can freely rotate. In embodiments, the magnetic connector 108 can have a body hole 157. The body hole 157 can accommodate the body 102. The securement of the body 102 to the magnetic connector 108 can be provided, for example, by a friction fit, or can be provided by any other suitable means including those described above with respect to other types of magnetic connectors 108. Adhesive can also be used to secure the body 102 in the magnetic connector 108. Although this particular magnet 120 configuration is depicted on the flexible body 102 of the construction unit 100, it should be understood that the magnet 120 configuration can be used on any construction unit 100 or on the flexible link 180 as desired.

[0116] As shown in FIG. 1, the kit 160 for constructing the structure 200 can include a plurality of individual construction units 100. Each of the construction units 100 can have a body 102 formed of a flexible material. As described above, the body 102 can have a first side 102 and a second side 104. Each construction unit 100 can have at least one magnetic connector 108 attached to the body 102. Figure 14

[0117] For example, the plurality of individual construction units 100 includes a first unit 162. The first unit 162 can have four arms 112 extending outwardly from the hub 110. Each arm 112 can have a free end 114. The plurality of magnetic connectors 108 can include at least four first unit magnetic connectors 108.

The plurality of magnetic connectors 108 can include at least two second unit magnetic connectors 108. Each of the second unit magnetic connectors 108 can be disposed adjacent to one of the free ends 114 of the elongate body 166. In certain embodiments, the second unit 164 can include three magnetic connectors 108.

[0119] ​The plurality of individual construction units includes a third unit 168. The third unit 168 can have a generally ovoid body 170. The ovoid body 170 can have a first end 172 and a second end 174. The plurality of magnetic connectors 108 can include a third unit magnetic connector 108. The third unit magnetic connector 108 can be disposed proximate the first end 172 of the generally ovoid body 170.

[0120] It should be appreciated that the kit 160 contemplated by the present application can include any suitable shape other than those depicted Figure 14 By way of non-limiting example, the kit 160 can include squares, rectangles, triangles, and circles.

[0121] Referring now to Figure 15A and 15B The kit 160 can further include at least one active unit 176 and at least one control unit 178. The active unit 176 can be configured to be in electronic communication with the control unit 176. The active unit 174 and the control unit 176 can each be further configured to be disposed on one of the magnetic connectors 108 of one of the construction units 100. It should be appreciated that the active unit 176 and the control unit 178 can be a single component of the kit 160 or two separate components.

[0122] The active unit 176 can include an input sensor (e.g., a proximity sensor or a light sensor, an orientation sensor, a sound sensor) or an output component with functional capabilities (e.g., at least one of sound, light, and motion). Advantageously, once the active unit 176 is activated, the plurality of construction units 108 will "come to life" with additional technical features (e.g., motion or lights).

[0123] The control unit 178 can be in electrical communication with a battery (not shown). The battery can be included in the control unit 178 component or can be provided as a separate unit. The control unit 178 can also have a microprocessor and memory. In a non-limiting example, the control unit 178 can be formed on a printed circuit board (PCB). The PCB can include conductive traces, pads, and other features etched from one or more copper sheets layers laminated onto and / or between sheet layers of a non-conductive substrate. The PCB can be single-sided (one copper layer), double-sided (two copper layers on both sides of one substrate layer), or multi-layered (external and internal copper layers alternating with substrate layers). Other suitable structures for PCBs can also be employed within the scope of the present application.

[0124] The memory can be provided in the form of a tangible, non-transitory processor-readable medium in communication with the microprocessor. The microprocessor can be adapted to execute instructions in the form of software tangibly encoded on the memory. The control unit 176 can be configured to selectively and automatically activate one of the active devices 176 in operation. The control unit 178 can also be configured to perform certain programmable actions, and permit a user to input said programmable instructions and store them on the memory of the control unit 178. In particular, the control unit 178 can include a human-machine interface, such as buttons, dials, touchscreens, etc., which allow the user to interact with the control unit 178 as desired.

[0125] In further embodiments, such as shown in Figures 25-26 , the active unit 176 and the control unit 178 can be provided as a single component, such as an electronics unit 179. The electronics unit 179 can be one of the construction units that also includes the structure and functionality of each of the active unit 176 and the control unit 178, such as shown in Figure 26 . More specifically, the electronics unit 179 can have the battery, the PCB with CPU, the magnetic sensor, and the active unit all contained within a single component or body. In certain embodiments, the active unit and the control unit can be attached to one of the construction units 101 to form the electronics unit 179. As non-limiting examples, the active unit and the construction unit can be attached via mechanical fasteners or chemical fasteners.

[0126] The electronics unit 179 can be configured to connect to the internet cloud and / or a mobile remote device, such as by using wireless transmission, such as Bluetooth. The electronics unit 179 can be equipped with a wireless transceiver for this purpose, for example. As a non-limiting example, the electronics unit 179 can also be activated from a remote device, such as a smartphone. Other suitable electronic transmission devices can also be used as desired.

[0127] The kit 160 can also include at least one flexible link 180, such as shown in Figure 15A . The flexible link 180 can include an insulated wire configured for placing the control unit 178 in electrical communication with the active unit 176. In one example, the flexible link 180 can be a flat PCB connector cable configured to connect to the PCB. However, the flexible link 180 can also be made with other suitable materials and configurations within the scope of the present application. It should be appreciated that the flexible link 180 can transmit power and signals or data.

[0128] In addition to the flexible link 180 being configured to place the active unit 176 in electrical communication with the control unit 178, the flexible link 180 can also be configured to be placed on a magnetic connector 108 of the construction unit 100. For example, the end of the flexible link 180 can have at least one magnetic connector 108 or can be formed of a material that can be magnetically attracted to a magnetic connector 108 of a construction unit. The flexible link 180 can thereby be connected directly to the active unit 176 or can be placed between the active unit 176 and the construction unit 100, with the active unit additionally connected to the construction unit 100 through the magnetic connector 108. Other suitable means for placing the active unit 176 in communication with the control unit 178 can be contemplated and can also be employed.

[0129] It should be appreciated that the flexible link 180 can be connected to other flexible links 180, control units 178, and construction units 100 in various configurations, for example as shown in Figure 15A The flexible link 180 can be provided with a split, for example. The split can allow the flexible link to be connected to multiple construction units 100. In addition, more than one flexible link 180 or more than one active unit 176 can be in electrical communication with one control unit 178. With the units connected, it should be appreciated that any rotation about the magnetic connectors of any of the units can not inhibit the transmission of power or signals or data. For example, power can be transmitted from the flexible link 180 to multiple magnetic connectors 108 that can be attached to the flexible link. Other suitable configurations can also be used as desired.

[0130] The kit 160 can include a plurality of accessories that can enhance the final structure constructed with the kit 160. The accessories can be used to expand the use and give the user more construction and play options.

The decorative clip can also be configured to hold a paper or other thin element comprising a body 102 of another one of the construction units 100. Advantageously, the decorative clip 186 can allow a user to decorate a structure with additional non-metallic or non-magnetic elements.

[0134] The present application also includes a method for constructing a structure 200, for example as shown in Figures 16-18 FIG. 39. The structure 200 can be flat or two-dimensional, or can be three-dimensional, depending on the user’s intent. While the structure 200 is shown as a simple cylinder in Figures 16-18 FIG. 39, it should be understood that the structure 200 can comprise many different structures of varying complexity. For example, the structure 200 can comprise a construction, an animal figurine, a robot, and a vehicle. Any other suitable construction units 100 can be selected by those skilled in the art to construct the structure 200 as desired.
