Technical Field

The invention relates to the field of toys, in particular to a functional building block component.

Background

Generally, a toy building set generally comprises a plurality of toy building elements, each of which is variously spliced to each other by a child, thereby realizing toy building models of different shapes and forms, and thus serving the purpose of developing intelligence and enjoying fun thereof for the child.

Disclosure of Invention

Under the above background, the present invention provides a functional block component, by which children who splice blocks can not only develop intelligence and splicing pleasure, but also realize corresponding additional functions. A functional building element, comprising: a first building element adapted to be inserted into a second building element; and a functional element housed in the first building element; wherein the functional element is activated when the first building element is plugged with the second building element.

Advantageously, the functional component may comprise: a power supply, a functional element, and a switching element. The power source may be configured as a battery, although other types of power sources suitable for mating building elements are contemplated. The power source, the functional element and the switch element may be electrically connected, wherein when the first building element is not plugged into the second building element, the switch element is in a normally-off state, and when the first building element is plugged into the second building element, the switch element is triggered to be in a closed state, so that the power source, the functional element and the switch unit form a closed loop, and the functional element is in an operating state.

Advantageously, the first building element may further comprise a first spigot and a second spigot. Wherein the second building element is configured to be plugged to a second plug. Wherein the switch element may be provided at a second plug, the switch element being triggered to a closed state when the second building element is plugged to the second plug.

Advantageously, the switch element may be configured as a spring plate which is urged to a closed state when the second building element is plugged to the second plug. The spring plate can be designed as a metal plate, such as a copper plate, but naturally other types of metal wires for electrical conduction are also conceivable. Naturally, other types of switching elements having the same function are also conceivable.

Advantageously, the second building element may comprise a third spigot adapted to be plugged to the second spigot, said third spigot pushing said resilient tab to the closed state when plugged to said second spigot. Wherein more advantageously the third plug is of the same construction as the first plug.

The first plug connector can be a male connector, the second plug connector can be a female connector, and the third plug connector is a male connector.

Advantageously, the functional component may further comprise: a support, which may be composed of an insulating material, for carrying the power supply, the functional element and the switching element.

Advantageously, the first building element may form a cavity, such that the bracket is adapted to be received and snap-fitted within said cavity. Advantageously, the functional element may be adapted to be replaced by removal of the power supply from the bracket after removal from the cavity of the first building element. Whereby a good detachability can be achieved.

Advantageously, the first building element may comprise a first plug and a second plug, wherein the first plug is a male plug and the second plug is a female plug. The second plug can be communicated with the cavity to form an opening, and the power supply, the functional element and the functional element can be installed on the support and form a functional component, and then the power supply, the functional element and the functional element are installed in the cavity of the first building block component from the second plug. This results in a simple and orderly installation and is less prone to misassembly and damage to the components.

Advantageously, the formed functional element mounted in the cavity of the first building element may be decomposed into said power source, functional element, switching element and support without damage after removal from the cavity of the first building element. Advantageously, the connection of the first plug of the first building element to the body thereof may have an opening through which the functional element mounted on the support may protrude into the first plug. Advantageously, the functional element projecting through the opening into the first spigot does not project beyond the end of the first spigot opposite the body of the first building element. This ensures that the presence of the functional element does not affect the insertion of the building blocks.

Furthermore, advantageously, the first plug may also be adapted to plug a fourth plug of a third building element, wherein the fourth plug may be of the same construction as the second plug.

Advantageously, in the case of a switching element formed as a metal sheet, one end of the switching element is connected to one end of the functional element, the other end of the functional element is connected to a first pole, for example, the positive pole, of the power source, the other end of the switching element is formed as a free contact spring end and is located at the bottom of the functional component as a whole, the second pole, i.e., the negative pole, of the power source is exposed at the bottom of the functional component as a whole, and the second building element pushes the contact spring end of the switching element in the direction of the bottom of the functional component into electrical connection with the second pole, i.e., the negative pole, of the power source when the first building element is plugged. Naturally, the first pole may be configured as a negative pole of the power supply, and the second pole may be configured as a positive pole of the power supply, in a manner opposite to that described above.

Advantageously, in another case, as also described above, the switching element is constructed as a metal sheet. Further, the power source may include a first power source and a second power source. Wherein one end of the switching element is connected to a first pole, e.g. the positive pole, of a first power supply; and a second pole of the first power supply is connected with one end of the functional element; and the other end of the functional element is connected to a first pole, e.g. a positive pole, of a second power supply; and a second pole of the second power source, that is, a negative pole, is exposed to a side surface of the whole functional member; and the other end of the switching element is configured as a free contact spring end, is located on the side surface of the entire functional member, and corresponds to the position of the second pole, that is, the negative pole, of the second power supply. Then, when the first building element is plugged into the second building element, the second building element pushes the contact spring end inwards in a direction perpendicular to the plugging direction, so that the contact spring end is electrically connected with the second pole of the second power source, namely the negative pole. Naturally, as also described above, the first pole may be configured as a negative pole of the power supply, and the second pole may be configured as a positive pole of the power supply.

Advantageously, the functional component can also comprise a connection line, which connection line and the switching element can both be formed as sheet metal. Wherein one end of the connection line is connected with a first pole, such as a positive pole, of a power supply; and the other end of the connecting line is connected with one end of the functional element; and the other end of the functional element is connected with one end of the switch element; and the other end of the switch element is formed as a free contact spring piece end and is positioned on the side surface of the whole functional component. Wherein a second pole, i.e., a negative pole, of the power supply is exposed to a side surface of the entire functional member; the free spring piece end corresponds to the second pole of the power supply, namely the negative pole. Therefore, when the first building element is plugged with the second building element, the second building element pushes the contact spring piece end inwards in the direction perpendicular to the plugging direction, so that the contact spring piece end is in contact with the second pole of the second power supply, namely the negative pole, to form electrical connection. Naturally, as also described above, the first pole may be configured as a negative pole of the power supply, and the second pole may be configured as a positive pole of the power supply.

Advantageously, the functional member may be an activatable light emitting luminaire. Therefore, when the first building element and the second building element are inserted into each other, the internal circuit of the light-emitting lamp is closed, and the light-emitting lamp is lightened and activated. Naturally, in this case, the first building element is of transparent or light-permeable construction, so that the light of the light-emitting luminaire can shine through the first building element.

Furthermore, the light fixtures can be designed as correspondingly adapted LED lamps, naturally other types of light fixtures suitable for toys are also conceivable. When the power supply, the switching element and the light emitting lamp are electrically turned on, the light emitting lamp is activated to emit light.

The idea behind the above-described embodiment is therefore that, when the first building element and the second building element are completely plugged together, the power supply, the switching element and the LED lamp are electrically switched on, so that the LED lamp is illuminated; on the contrary, when the first building element and the second building element are not plugged with each other, the power supply, the switch element and the LED lamp are electrically disconnected, so that the LED lamp is in a non-working state, i.e., a non-light-emitting state.

Advantageously, it is naturally also conceivable that the functional component can be designed as another type of functional component, such as a loudspeaker, a music player module, etc. Thus, when the first and second building elements are not completely plugged together, the corresponding speakers, music playing modules, etc. are in an inactive state and do not perform the corresponding functions; conversely, when the first and second building elements are completely plugged into each other, the respective speaker and music playing module are activated to start performing the respective function, such as sounding or playing the respective music, and so on.

Detailed Description

The functional building element 100 proposed according to the invention is elucidated in detail below on the basis of three specific embodiments. In these three embodiments, the functional building element 100 comprises: a first building element 10 and a functional element 30, wherein the first building element 10 is adapted to be plugged into a second building element 20, wherein the functional element 30 is received in the first building element 10, and wherein the functional element 30 is activated in case the first building element 10 and the second building element 20 are completely plugged into each other. Wherein according to these three embodiments the first building element 10 and the second building element 20 have mutually identical male and female heads, respectively, so that a mutual plugging can be achieved.

In particular, the first and

second building elements

10, 20 may be formed as hollow cylinders having male and female elements that are insertable into each other as a whole and made of an insulating material, such as plastic. The functional component 30 can be designed as an activatable light fixture 30.

Specifically, the light emitting lamp 30 may include a power source 1, a light emitting element 2, a bracket 3, and a switching element 4. Wherein a cavity is formed at the lower part of the first building element 10, and the bracket 3 is suitable for being accommodated and clamped in the cavity. In addition, the female part of the first building element 10 is connected to the middle cavity to form an opening, and the power source 1, the functional element 2 and the switching element 4 can be mounted on the bracket 3 to form the functional element 30, and then mounted in the cavity of the first building element 10 through the female part. It goes without saying that the functional element 30, which is inserted into the cavity of the first building element 10 via the female connector, can naturally be separated without damage into the power supply 1, the functional element 2, the switching element 4 and the holder 3 after it has been removed from the cavity of the first building element 10. In this case, therefore, it is appropriate to detach the power supply 1 from the stand 3 in this manner for replacement.

Fig. 1a shows an exploded view of a light emitting luminaire 30 as a functional component 30 of a functional building element 100 according to a first embodiment of the present invention. The power source 1 is constituted by two batteries 1 connected in series up and down. The switching element 4 is formed as a copper metal sheet 4. The carrier 3 is made of an insulating material and serves to support the battery 1, the switching element 4 and the light-emitting element 2, which is designed as an LED. When the battery 1, the switching element 4, and the LED lamp 2 are electrically turned on, the LED lamp 2 is activated and emits light.

Fig. 1b and 1c show schematic cross-sectional construction views of a functional building element 100 according to a first embodiment of the invention in two states. Fig. 1b shows a schematic view of the functional building element 100 in a state in which the first building element 10 is not plugged into the second building element 20, wherein it can be seen that the upper end of the switching element 4 is connected to one end of the LED lamp 2, while the other end of the LED lamp is connected to the positive pole of the upper one of the two series-connected batteries 1, and furthermore the other end of the switching element 4 is configured as a free contact spring end and is located at the bottom of the light fixture 30 as a whole and hangs down slightly at an acute angle, so as to remain out of contact with the negative pole of the lower one of the batteries 1, so that the internal circuit of the light fixture 30 as a whole remains open, while the LED lamp 2 is in an inactive state and does not emit light. When the first building element 10 is inserted into the second building element 20, the second building element 20 pushes the free contact spring end of the switch element 4 toward the bottom of the light-emitting lamp 30 to contact with the negative electrode of the power source 1 to form an electrical connection. Of course, in other embodiments, the positive and negative mounting directions of the power supply 1 may be interchanged.

As can be seen in fig. 1c, when the second building element 20, i.e. its male portion, is inserted from below into the first building element 10, i.e. its female portion, and is completely inserted into place, the contact spring ends, which in fig. 1b are in a slightly downwardly drooping state, are brought upwards and into contact with the negative pole of the battery below by pressing against the top of the male portion of the second building element 20, so that the internal circuit of the light emitting lamp 30 is closed, and the LED lamp 2 is activated and emits light. That is, it is not necessary that the second building element 20 has any electrical structure, as long as the male part of the second building element 20 is plugged into the female part of the first building element 10, the circuit of the light emitting lamp 30 in the first building element 10 is closed, and a loop is formed by itself, so that the LED lamp 2 is activated and emits light. And the male part of the first building element 10 is of the same construction as the male part of the second building element 20, the female part of the first building element 10 is of the same construction as the female part of the second building element 20, even the first building element 10 is of the same construction as the second building element 20, i.e. the first building element 10 and the second building element 20 may be standard parts which can be interchanged without special changes or designs to the building elements or the male and female parts.

Furthermore, as can be seen from fig. 1c, the junction of the male part of the first building element 10 with its body has an opening through which the functional element 2 mounted on the holder 3, i.e. the LED lamp 2, protrudes into the male part, through which opening the light emission of the LED lamp 2 can also propagate out of the first building element 10. When the male part of the first building element 10 is plugged into a further transparent or light-permeable third building element, the light emitted by the LED lamp 2 can also shine through the third building element. Of course, the first building element 10 itself may also be transparent, and the light emitted by the LED lamp 2 may shine through the first building element 10. Furthermore, the LED lamp 2 protruding through the opening into the male portion does not extend beyond the end of the male portion opposite the body of the first building element 10, which on the one hand serves to protect the LED lamp 2 and on the other hand does not affect the insertion of the male portion of the first building element 10 into another building element.

Fig. 2a shows an exploded view of a light emitting lamp 30 as a functional component 30 of a functional building element according to a second embodiment of the invention. The power source 1 is configured of two batteries 1 which are provided on the left and right sides but are not directly connected in series. The switching element 4 is likewise formed as a copper metal sheet 4. The holder 3 is likewise made of an insulating material and serves to support the battery 1, the switching element 4 and the light-emitting element 2, which is in the form of an LED. Also as in the first embodiment, when the battery 1, the switching element 4, and the LED lamp 2 are electrically turned on, the LED lamp 2 is activated and emits light. That is, it is not necessary that the second building element 20 has any electrical structure, as long as the male part of the second building element 20 is plugged into the female part of the first building element 10, the circuit of the light emitting lamp 30 in the first building element 10 is closed, and a loop is formed by itself, so that the LED lamp 2 is activated and emits light. And the male part of the first building element 10 is of the same construction as the male part of the second building element 20, the female part of the first building element 10 is of the same construction as the female part of the second building element 20, even the first building element 10 is of the same construction as the second building element 20, i.e. the first building element 10 and the second building element 20 may be standard parts which can be interchanged without special changes or designs to the building elements or the male and female parts.

Fig. 2b and 2c show schematic cross-sectional construction views of a functional building element 100 according to a second embodiment of the invention in two states. Fig. 2b shows a schematic view of the building element 100 in a state in which the first building element 10 is not plugged into the second building element 20, wherein one end of the switching element 4 is connected to the negative pole of the right-hand battery 1, the positive pole of the right-hand battery 1 is connected to one end of the LED lamp 2, the other end of the LED lamp 2 is connected to the negative pole of the left-hand battery 1, and furthermore the other end of the connecting line 4 is formed as a free contact spring end on the side of the light fitting 30 as a whole (on the left in fig. 2 b) and remains out of contact with the other electrical components, in particular the positive pole of the left-hand battery 1 in the battery 1, so that the internal circuit of the light fitting 30 as a whole remains open, while the LED lamp 2 is in an inactive state and does not. The positive electrode of the left battery 1 is exposed to the side surface of the entire light emitting lamp 30 and the position thereof corresponds to the end position of the contact spring piece of the switch element 4 configured to be free.

When the first building element 10 is inserted from below into the second building element 20 and is completely inserted into place, as shown in fig. 2c, the contact dome ends, which are free in fig. 2b, are deflected inwardly and brought into contact with the positive pole of the left battery 1 by the pressure of the top of the second building element 20, so that the internal circuit of the light fixture 30 is closed, so that the LED lamp 2 is activated and emits light. Of course, in other embodiments, the positive and negative mounting directions of the power supply 1 may be interchanged.

Furthermore, as can be seen from fig. 2c, the junction of the male part of the first building element 10 with its body has an opening through which the functional element 2 mounted on the holder 3, i.e. the LED lamp 2, protrudes into the male part, through which opening the light emission of the LED lamp 2 can also propagate out of the first building element 10. When the male part of the first building element 10 is plugged into a further transparent or light-permeable third building element, the light emitted by the LED lamp 2 can also shine through the third building element. Of course, the first building element 10 itself may also be transparent, and the light emitted by the LED lamp 2 may shine through the first building element 10. Furthermore, the LED lamp 2 protruding through the opening into the male portion does not extend beyond the end of the male portion opposite the body of the first building element 10, which on the one hand serves to protect the LED lamp 2 and on the other hand does not affect the insertion of the male portion of the first building element 10 into another building element.

Furthermore, fig. 3a shows an exploded view of a light emitting lamp 30 as a functional component 30 of a functional building element according to a third embodiment of the present invention. As in the first embodiment, the power supply 1 is configured by two batteries 1 connected in series on the left and right. The switching element 4 is also constructed as a copper metal sheet 4, and differs from the above-described second embodiment in that the functional member 30 further includes a connection wire, and the connection wire and the switching element 4 are both metal sheets. The holder 3 is likewise made of an insulating material and serves to support the battery 1, the switching element 4, the connecting lines and the light-emitting element 2, which is designed as an LED. Also as in the first and second embodiments, in the case where the battery 1, the switching element 4, the connection line, and the LED lamp 2 are electrically turned on, the LED lamp 2 is activated and emits light. That is, it is not necessary that the second building element 20 has any electrical structure, as long as the male part of the second building element 20 is plugged into the female part of the first building element 10, the circuit of the light emitting lamp 30 in the first building element 10 is closed, and a loop is formed by itself, so that the LED lamp 2 is activated and emits light. And the male part of the first building element 10 is of the same construction as the male part of the second building element 20, the female part of the first building element 10 is of the same construction as the female part of the second building element 20, even the first building element 10 is of the same construction as the second building element 20, i.e. the first building element 10 and the second building element 20 may be standard parts which can be interchanged without special changes or designs to the building elements or the male and female parts.

Fig. 3b and 3c show schematic cross-sectional construction views of a functional building element 100 according to a third embodiment of the invention in two states. FIG. 3b shows a schematic view of the building element 100 in a state where the first building element 10 is not plugged into the second building element 20, wherein one end of the visible connection line (left side part in FIG. 3 b) is connected to the negative pole of the left battery 1 and the other end is connected to one end of the LED lamp 2 (left side end in FIG. 3 b); while the other end (right end in fig. 3 b) of the LED lamp 2 is connected to one end (upper end) of the switching element 4 (right part in fig. 3 b), and the other end (lower end) of the switching element 4 is configured as a free contact spring end and is kept out of contact with other electrical components, in particular, the positive electrode of the right battery 1 in the battery 1, so that the internal circuit of the light emitting lamp 30 as a whole is kept open, while the LED lamp 2 is in an inactive state and does not emit light. Wherein, the negative pole of the right battery 1 is exposed to the side of the whole light-emitting lamp 30, and the free spring end corresponds to the positive pole of the right battery 1.

As shown in fig. 3c, when the first building element 10 is inserted into the second building element 20 from below and is completely inserted into place, the contact spring ends, which are free in fig. 2b, are displaced inwardly by the pressure of the top of the second building element 20 and come into contact with the positive pole of the left battery 1 (corresponding to the right battery 1 in fig. 3 b), so that the internal circuit of the functional element 30 is closed and the LED lamp 2 is activated and emits light. Of course, in other embodiments, the mounting directions of the positive and negative electrodes of the power supply 1 may be replaced.

Furthermore, as can be seen from fig. 3c, the junction of the male part of the first building element 10 with its body has an opening through which the functional element 2 mounted on the holder 3, i.e. the LED lamp 2, protrudes into the male part, through which opening the light emission of the LED lamp 2 can also propagate out of the first building element 10. When the male part of the first building element 10 is plugged into a further transparent or light-permeable third building element, the light emitted by the LED lamp 2 can also shine through the third building element. Of course, the first building element 10 itself may also be transparent, and the light emitted by the LED lamp 2 may shine through the first building element 10. Furthermore, the LED lamp 2 protruding through the opening into the male portion does not extend beyond the end of the male portion opposite the body of the first building element 10, which on the one hand serves to protect the LED lamp 2 and on the other hand does not affect the insertion of the male portion of the first building element 10 into another building element.

Naturally, it is also conceivable that the functional component can be designed as another type of functional component, such as a loudspeaker, a music player module, etc. Thus, when the first and second building elements are not completely plugged together, the corresponding speakers, music playing modules, etc. are in an inactive state and do not perform the corresponding functions; conversely, when the first and second building elements are completely plugged into each other, the respective speaker and music playing module are activated to start performing the respective function, such as sounding or playing the respective music, and so on.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. It should be understood that the features disclosed in the above embodiments may be used alone or in combination, except where specifically noted. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
