Description

Technical Field

[0001] This application belongs to the technical field of charging devices, and particularly relates to a charging combination with a power socket and expansion interface functions. Background Art

[0002] With the rapid development of technology, continuously evolving mobile devices such as smartphones, smart wearable devices, tablet computers, and laptop computers are all dedicated to business or private communication, communication, photography, and computing needs. With the gradual popularization of these mobile devices, people are usually in multi-demand application scenarios when outside. For example: Mobile devices are all restricted by the battery capacity and need to be charged in time to maintain the battery life; or, these mobile devices have the need to connect to other devices for data transmission, but the data ports of different devices are different, resulting in connection adaptability problems of data ports; or, the types of power plugs on different devices are different, and corresponding power sockets and electrical sockets are required. These are all common needs in the application scenarios that people often encounter when traveling far away, such as on business trips or traveling.

[0003] Therefore, people need to carry corresponding auxiliary devices according to the usage requirements. For the above-mentioned complex application scenarios, auxiliary devices such as chargers, docking stations, and universal sockets are required. These auxiliary devices are all independent devices, and carrying all of them will occupy a large storage space and is not conducive to carrying them at the same time. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a charging combination to solve the technical problem that the peripherals of existing mobile devices have poor integration and are not conducive to people carrying them at the same time when going out.

[0005] To achieve the above purpose, the technical solution adopted in this application is: providing a charging combination, including a charger and an electrical socket that can be combined and connected.

[0006] The charger is provided with an expansion interface and a pair of electrical insertion pieces that can be rotated, extended, or retracted. The pair of electrical insertion pieces are arranged to be electrically connected to the electrical socket when retracted.

[0007] The electrical socket is provided with terminal sockets, electrical insertion cylinders, a cable and a plug for connecting to a power source. The number of the electrical insertion cylinders is the same as that of the electrical insertion pieces, and they are horizontally arranged on the combined connection end of the electrical socket; when the charger is combined and connected to the electrical socket, the electrical insertion cylinders and the electrical insertion pieces are horizontally inserted into each other.

[0008] The beneficial effects of the charging combination provided by this application are as follows: Compared with the prior art, the charging combination of this application includes a charger and an electrical socket, which can be combined and connected together, facilitating simultaneous portability when going out. After the two are separated, the charger can be used alone and can be directly connected to the power supply through the pair of electrical plug blades. The charger also integrates the function of a docking station, and there are expansion interfaces on the charger, which can be used as a docking station at the same time. In addition, the electrical socket can also be used alone as a universal socket, and there are various terminal sockets on the electrical socket, which is conducive to adapting to different types of power plugs and can meet the power connection needs of different terminals.

[0009] Among them, the combined connection structure between the charger and the electrical socket is improved. The pair of electrical plug blades on the charger are set to be used for electrical connection with the electrical socket only in the storage state. Correspondingly, there is a horizontally arranged electrical plug barrel on the combined connection end of the electrical socket. When the charger and the electrical socket are combined and connected, the electrical plug barrel and the electrical plug blades are inserted horizontally to make the charger and the electrical socket combined and connected in place, thereby forming a buckling structure between the charger and the electrical socket, making the two pull and fix each other, effectively preventing the charger and the electrical socket from being easily separated, and further improving the combined connection stability between the charger and the electrical socket.

[0010] The structure of the combined connection part between the charger and the electrical socket is improved. The charger has a first mating end for combined connection, and the electrical socket has a second mating end for combined connection with the charger. Both the first mating end and the second mating end have recesses and protrusions with matching shapes; among them, the socket on the electrical plug barrel is located on the recess of the second mating end. In this way, not only is the combined connection method of the first mating end and the second mating end unique, but also the mating parts can complement each other. It is beneficial to limit the splicing direction of the charger and the electrical socket to play an anti-fooling role when the two are combined and connected.

[0011] In one embodiment, the protrusion is a shoulder located on both sides of the pair of electrical plug blades or the electrical plug barrel, and the protrusion is adjacent to the recess to form a high and low wave part. This makes the connection part have a smooth transition, makes the combined connection operation smoother, and further improves the operation feel and aesthetic feeling.

[0012] The combined connection part on the charger is optimized. The charger is provided with a surrounding rib arranged around the outer periphery of the pair of electrical plug blades, and there is a side opening on the surrounding rib; one end of the electrical plug blade is arranged within the range surrounded by the surrounding rib through a rotating part, and the other end of the electrical plug blade extends towards the side opening of the surrounding rib during storage. The surrounding rib is used to protect the electrical plug blades from the outside periphery, effectively preventing accidental touch or foreign objects from entering, avoiding easy occurrence of short circuits, and improving the protection effect on the electrical plug blades.

[0013] In one embodiment, the surrounding rib extends to the recess on the first fitting end, and the protruding height of the surrounding rib on the charger is the same as that of the convex part on the first fitting end. In this way, the surrounding rib is used to fill the recess on the first fitting end to make the entire first fitting end flat, effectively ensuring the electrical connection stability when the charger is used alone.

[0014] In one embodiment, the electrical socket has shoulders surrounding both sides of the electrical insertion cylinder, and a slot for inserting the surrounding rib is formed by an interval between the electrical insertion cylinder and the shoulders. Using the surrounding rib and the slot as the operation objects for automatic alignment, there is no need to directly operate the electrical insertion piece and the electrical insertion cylinder for alignment and error testing, effectively avoiding miscontact or short-circuit faults that are likely to occur, and thus improving the operation efficiency of combined connection.

[0015] In one embodiment, a separating shaft is further provided on the charger within the range surrounded by the surrounding rib, and the separating shaft is located between the pair of electrical insertion pieces; the electrical insertion cylinders on the electrical socket are arranged at intervals to form a linear slot for inserting the separating shaft. In this way, the separating shaft plays a separating role between the pair of parallelly extending electrical insertion pieces. At the same time, the separating shaft is installed and aligned with the linear slot between the two electrical insertion cylinders to improve the installation guiding effect.

[0016] In one embodiment, a protruding guiding structure is further provided on the separating shaft, and the electrical insertion cylinder has a sliding groove for the guiding structure to slide into, further improving the connection compactness and fixing effect between the charger and the electrical socket.

[0017] In one embodiment, the guiding structure is convex ribs symmetrically arranged on both sides of the separating shaft, and the electrical insertion cylinders are provided with the sliding grooves on the side surfaces of the linear slot. In this way, both sides of the separating shaft can be symmetrically aligned and matched with the sliding grooves on the two electrical insertion cylinders, thereby improving the accuracy of installation alignment.

[0018] Improvements are made to the overall structures of the charger and the electrical socket. The charger is a cylindrical structure, and the first fitting end and the expansion interface are respectively arranged on opposite end faces of the charger; the shape of the electrical socket is similar to that of the charger, the second fitting end and the cable are respectively arranged on opposite end faces of the electrical socket, and the terminal sockets are distributed on the outer periphery of the electrical socket to maximize the use of the available space on the electrical socket to set the terminal sockets, which is convenient for users to select and use, and thus improves the applicability of the electrical socket. In addition, the first fitting end and the expansion interface are respectively arranged on opposite end faces of the charger, so that the expansion interface can face upward when the charger is used alone, which is convenient for selectively making electrical connections with other devices.

[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0040] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0041] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0042] With the gradual popularization of mobile devices, people are usually in multi-demand application scenarios when they are outside. Traditional chargers, docking stations, universal sockets, etc. are all independent devices, with a large variety and quantity, occupying a relatively large storage space and being inconvenient to carry outside at the same time.

[0043] In related technologies, there are solutions to directly add a docking station or charger to a power strip. Generally, connection terminals are set on the docking station, or the electrical plug terminals on the charger are directly plugged into a terminal socket of the power strip, so that the docking station or charger is fixed on the power strip for convenient carrying together. However, the electrical plug terminals on this charger or the added connection terminals on the docking station are all blade-shaped plug-in ends, which are then vertically inserted into the slots of the power strip. Due to the lack of an interlocking structure, it is easy to separate under the action of the weight of the docking station or charger itself, resulting in the easy detachment of the docking station or charger, and it is easy to cause damage or loss.

[0044] To improve the connection stability, the current solution is to increase the strength of the clips in the slots of the power strip so that the clips can clamp the inserted terminals. However, this will make it more laborious for users to plug in or unplug the docking station or charger, and the user experience is poor.

[0045] Therefore, the embodiments of the present application provide a new type of charging combination. The components in the charging combination adopt a highly integrated design, and the components are connected to each other by a combined manner, effectively meeting the requirements of people's composite application scenarios outside; and, the combined connection method is redesigned to make the combined connection structure more firm and convenient to use, effectively solving the technical problems that the traditional mobile device peripherals have poor integration and are not conducive to people carrying them outside at the same time. Now, a detailed description will be given.

[0046] Please refer to Figure 1 and Figure 2 together. The charging combination includes a charger 1 and an electrical socket 2. The charger 1 and the electrical socket 2 can be combined and connected together for convenient carrying outside at the same time.

[0047] Please refer to Figure 1 , Figure 3 and Figure 4 together. The charger 1 has an expansion interface 11 and a pair of electrical plug pieces 12. The pair of electrical plug pieces 12 are the charging terminals on the charger 1 and are arranged on the charger 1 through a rotating member 121, so that the pair of electrical plug pieces 12 can make a rotational movement on the charger 1 for convenient storage or extension on the charger 1. In this embodiment, the pair of electrical plug pieces 12 are set to be used for electrical connection with the electrical socket 2 only in the storage state.

[0048] As Figure 1 and Figure 2As shown, the charger 1 may have multiple expansion interfaces 11, and these expansion interfaces 11 are data ports of different types. The types of these data ports may include, but are not limited to, TYPE-C, USB, HDMI, etc., so as to adapt to different mobile terminals for data connection. Each expansion interface 11 may include one or more, and may be specifically set according to the volume of the charger 1 or the available space on the charger 1, and no specific limitation is made here.

[0049] Please refer to Figure 1 and Figure 2 , the electrical socket 2 has terminal sockets 21, an electrical socket barrel 3, and cables 22 and plugs 23 for connecting to a power source. The cables 22 and plugs 23 are traditional power connection configurations, and the plug 23 can be used to connect to an AC power source. The cable 22 is preferably a flexible cable, so that the cable 22 can be coiled for convenient storage, and the length of the cable 22 can be set according to the usage requirements.

[0050] There are multiple and different types of terminal sockets 21, such as traditional two-socket and three-socket types, etc. These sockets can be arranged individually, or the two-socket and three-socket positions can be overlapped. For the setting method and layout form of these terminal sockets 21 on the electrical socket 2, it can be set according to the usage requirements, and no specific limitation is made here.

[0051] The electrical socket barrel 3 on the electrical socket 2 is used for the power plug piece 12 of the charger 1 to be inserted to achieve electrical connection. The number of the electrical socket barrels 3 is the same as that of the power plug pieces 12, and the layout of the electrical socket barrels 3 on the electrical socket 2 is the same as the setting form of this pair of power plug pieces 12, that is, two electrical socket barrels 3 extend parallel in the same direction.

[0052] Among them, the electrical socket barrel 3 is horizontally arranged on the combined connection end of the electrical socket 2. Here, it can be understood that when the electrical socket 2 is vertically arranged (such as Figure 5 shown, that is, when the combined connection end of the electrical socket 2 is in the placement state at the bottom of the electrical socket 2), the electrical socket barrel 3 is horizontally arranged on this combined connection end. As Figure 5 shown, that is, it is arranged on the combined connection end of the electrical socket 2 in a form where the extension direction F of the electrical socket barrel 3 is perpendicular to the central axis S of the electrical socket 2.

[0053] When the charger 1 and the electrical socket 2 are combined and connected, as Figure 6 shown, the electrical socket barrel 3 and the power plug piece 12 adopt a horizontal plug-in manner to make the charger 1 and the electrical socket 2 combined and connected in place, so that the electrical socket barrel 3 and the power plug piece 12 can be fixed to each other in a manner similar to snap connection to prevent detachment.

[0054] Compared with the prior art, the charging combination provided by the embodiments of the present application includes a charger 1 and an electrical socket 2, which can be combined and connected together, facilitating simultaneous portability when going out. After the two are separated, the charger 1 can be used alone, and the power supply can be directly connected through the pair of electrical plug blades 12. The charger 1 also integrates the function of a docking station, and there is an expansion interface 11 on the charger 1, which can be used as a docking station at the same time. The electrical socket 2 can also be used alone as a universal socket 2, and there are various terminal sockets 21 on the electrical socket 2, which is beneficial to adapt to different types of power plugs 23 and can meet the power connection requirements of different terminals.

[0055] Among them, the combined connection structure between the charger 1 and the electrical socket 2 is improved. The pair of electrical plug blades 12 on the charger 1 are set to be used for electrical connection with the electrical socket 2 only in the stored state. Correspondingly, there is a horizontally arranged electrical plug cylinder 3 on the combined connection end of the electrical socket 2, so that when the charger 1 and the electrical socket 2 are combined and connected, the electrical plug cylinder 3 and the electrical plug blades 12 are inserted horizontally to make the charger 1 and the electrical socket 2 combined and connected in place.

[0056] It can be seen that the entire combined connection operation is as follows: First, place the charger 1 and the electrical socket 2 in a misaligned position, then align the electrical plug cylinder 3 on the electrical socket 2 with the electrical plug blades 12 on the charger 1, and move them towards each other until they are successfully plugged in place, and then align the charger 1 and the electrical socket 2 coaxially to complete the combined connection.

[0057] In this way, by using the horizontal insertion of the electrical plug cylinder 3 and the electrical plug blades 12, a buckling structure is formed between the charger 1 and the electrical socket 2, so that the two are tightened and fixed to each other, effectively preventing the charger 1 and the electrical socket 2 from being easily separated, and thus improving the combined connection stability between the charger 1 and the electrical socket 2.

[0058] For the specific structure of the combined connection part between the charger 1 and the electrical socket 2, in an embodiment of the present application, please refer to Figure 7 、 Figure 8 and Figure 9 , the charger 1 has a first splicing end 13 for combined connection, and the electrical socket 2 has a second splicing end 24 for combined connection with the charger 1. The charger 1 and the electrical socket 2 can be spliced together through the first splicing end 13 and the second splicing end 24 to form a whole, which is convenient for users to store.

[0059] In this embodiment, both the first fitting end 13 and the second fitting end 24 are provided with a recess 41 and a protrusion 42 that are shape-matching, so that the contours of the portions where the first fitting end 13 and the second fitting end 24 are spliced together match. In this way, not only is the combination connection method of the first fitting end 13 and the second fitting end 24 unique, but also the spliced portions can complement each other to be complete. This is beneficial for defining the splicing direction of the charger 1 and the electrical socket 2, so as to play an anti-misconnection role when the two are combined and connected.

[0060] Among them, as Figure 8 shown, the socket on the electrical plug barrel 3 is located on the recess 41 of the second fitting end 24, which facilitates the electrical plug blade 12 to be easily aligned with the socket of the electrical plug barrel 3 at this position and horizontally inserted into the electrical plug barrel 3, so that the charger 1 and the electrical socket 2 are simultaneously combined and connected in place.

[0061] In this embodiment, as Figure 8 and Figure 9 shown, the protrusion 42 is preferably a shoulder 42a located on both sides of a pair of electrical plug blades 12 or the electrical plug barrel 3. The protrusion 42 and the recess 41 are adjacent and connected to form a high-low wavy portion. In this way, the connection portion between the protrusion 42 and the recess 41 has a smooth transition, so that the combined connection operation is smoother, thereby improving the operation feel and aesthetic sense.

[0062] To optimize the combined connection portion on the charger 1, in an embodiment of the present application, please refer to Figure 7 and Figure 8 together. A surrounding rib 5 is provided on the charger 1 around the outer periphery of a pair of electrical plug blades 12. The surrounding rib 5 is used to surround and protect the electrical plug blades 12 from the outer periphery, thereby preventing accidental touch or foreign objects from getting in, effectively preventing the electrical plug blades 12 from being easily short-circuited, and further improving the protection effect on the electrical plug blades 12.

[0063] A side opening 50 is provided on the surrounding rib 5. One end of the electrical plug blade 12 is arranged within the surrounding range of the surrounding rib 5 through a rotating member 121, and the other end of the electrical plug blade 12 extends towards the side opening 50 of the surrounding rib 5 when being stored. In this way, when the charger 1 and the electrical socket 2 are combined and connected, the electrical plug blade 12 can be smoothly inserted into the electrical plug barrel 3 by using the side opening 50 of the surrounding rib 5.

[0064] In practical applications, when the charger 1 is used alone, a pair of electrical inserts 12 on the charger 1 will be separated to be inserted into a common power socket. As an example, in a usage scenario, a power socket is generally provided on the multi-functional conference table in a meeting room. When the charger 1 is plugged into this power socket, the combined connection part of the charger 1 (i.e., the first fitting end 13) will abut against the power socket as a base. However, on the charger 1 provided in the embodiment of the present application, the first fitting end 13 has an adjacent concave portion 41 and convex portion 42. Among them, the concave portion 41 will form a vacancy at the bottom of the charger 1, which will cause the entire charger 1 to be unstable when placed and affect the power connection stability of the charger 1.

[0065] For this reason, in an embodiment of the present application, please refer to Figure 9 and Figure 10 together. The rib 5 on the charger 1 extends to the concave portion 41 of the first fitting end 13, and the protruding height H1 of the rib 5 on the charger 1 is the same as the height H2 of the convex portion 42 on the first fitting end 13.

[0066] In this way, the rib 5 fills the concave portion 41 of the first fitting end 13, and the rib 5 is used as a support at the bottom of the charger 1, thereby making up for the vacancy at the bottom of the charger 1 and making the entire first fitting end 13 flat, effectively ensuring the electrical connection stability when the charger 1 is used alone.

[0067] In another embodiment of the present application, please refer to Figure 7 and Figure 8 together. The electrical socket 2 has shoulders 42a surrounding both sides of the electrical socket cylinder 3, and a slot 43 for inserting the rib 5 is formed by arranging the electrical socket cylinder 3 and the shoulders at intervals.

[0068] When the charger 1 and the electrical socket 2 are combined and connected, the side opening 50 of the rib 5 can be first aligned with the position of the slot 43 on the electrical socket 2, and then the rib 5 is slid along the slot 43 until it is installed in place, while the electrical inserts 12 and the electrical socket cylinder 3 are automatically aligned and the horizontal insertion is successfully completed.

[0069] In this way, the rib 5 and the slot 43 are used as the operation objects for automatic alignment, without directly operating the electrical inserts 12 and the electrical socket cylinder 3 for alignment and trial and error, effectively avoiding miscontact or short-circuit faults that are likely to occur, and thus improving the operation efficiency of the combined connection.

[0070] To further optimize the combined connection part on the charger 1, in an embodiment of the present application, please refer to Figure 8 , Figure 11 and Figure 12, a partition shaft 51 is further provided on the charger 1 within the range surrounded by the rib 5, and the partition shaft 51 is located between a pair of electrical plug blades 12. Correspondingly, a linear slot 44 for inserting the partition shaft 51 is formed by arranging the two electrical plug cylinders 3 on the electrical socket 2 at intervals.

[0071] On the one hand, the partition shaft 51 is arranged between the ribs 5, and the partition shaft 51 is used to separate between a pair of parallelly extending electrical plug blades 12, so as to prevent the conductive foreign objects that have penetrated here from just simultaneously touching the two electrical plug blades 12 to cause a short circuit.

[0072] On the other hand, the partition shaft 51 is arranged parallel to the pair of electrical plug blades 12 in the received state in the same direction, so that the partition shaft 51 can be used as a guide shaft. When the charger 1 and the electrical socket 2 are combined and connected, the partition shaft 51 is aligned with the linear slot 44 between the two electrical plug cylinders 3, and while sliding along the linear slot 44, a pair of electrical plug blades 12 and the two electrical plug cylinders 3 are respectively automatically aligned, and the horizontal insertion operation is successfully completed, thus playing a role of installation guidance.

[0073] Preferably, please refer to Figure 11 and Figure 12 , a guiding structure provided with a protrusion can be further arranged on the partition shaft 51; correspondingly, a sliding groove 31 for the guiding structure to slide into is provided on the electrical plug cylinder 3.

[0074] When the charger 1 and the electrical socket 2 are combined and connected, the guiding structure also simultaneously slides into the sliding groove 31 of the electrical plug cylinder 3, and slides synchronously with the partition shaft 51 until it is installed in place, so as to further improve the connection tightness and fixing effect between the charger 1 and the electrical socket 2.

[0075] Specifically, in this embodiment, as Figure 11 shown, the guiding structure can preferably be convex ribs 52 symmetrically arranged on both sides of the partition shaft 51, the convex ribs 52 extend along the length direction of the partition shaft 51, and the length of the convex ribs 52 is preferably set to be not greater than the length of the partition shaft 51.

[0076] The sliding groove 31 is provided on the side surface of the electrical plug cylinder 3 located on the side of the linear slot 44. It can be understood that the sliding groove 31 is opened on the opposite side surfaces between the two electrical plug cylinders 3, and the convex ribs 52 can slide into the sliding groove 31 until they are installed in place.

[0077] In this way, the two sides of the partition shaft 51 can be symmetrically aligned and matched with the sliding grooves 31 on the two electrical plug cylinders 3, thereby improving the accuracy of installation alignment and the connection tightness between the charger 1 and the electrical socket 2.

[0078] In other embodiments (not shown in the figures), the guiding structure may also be other structures protruding on the separating axis 51, as long as they can slide into the sliding groove 31 on the electric plug barrel 3, and no specific limitation is made here.

[0079] For the overall structures of the charger 1 and the electrical socket 2, in one embodiment of the present application, please refer to Figure 1 、 Figure 2 and Figure 3 together. The charger 1 is preferably a cylindrical structure, specifically a rectangular cylinder with arc-shaped edges, so as to have more available space inside, facilitate the layout of internal electrical components, and effectively improve the utilization rate of the available space inside the charger.

[0080] As Figure 6 and Figure 7 shown, the first fitting end 13 and the expansion interface 11 on the charger 1 are respectively arranged on opposite end faces of the charger 1. In this embodiment, the first fitting end 13 and the expansion interface 11 are respectively arranged on the upper and lower end faces of the charger 1, and the expansion interface 11 is arranged in two columns on the end face of the charger 1, so that when the charger 1 is used alone, the expansion interface 11 on this end face faces upward, facilitating selective electrical connection with other devices.

[0081] As Figure 2 shown, the shape of the electrical socket 2 is similar to that of the charger 1. The second fitting end 24 and the cable 22 of the electrical socket 2 are respectively arranged on opposite end faces of the electrical socket 2, and the terminal sockets 21 are distributed on the outer periphery of the electrical socket 2.

[0082] In this embodiment, the second fitting end 24 and the cable 22 are respectively arranged on the upper and lower end faces of the electrical socket 2. The cable 22 extends outward from one end face of the electrical socket 2, and the distal end of the cable 22 has a plug 23 for connecting to a power supply.

[0083] The terminal sockets 21 on the electrical socket 2 are distributed on the outer periphery of the electrical socket 2. In this embodiment, the shape of the electrical socket 2 is similar to that of the charger 1, and it can be preferably a rectangular cylinder structure with arc-shaped edges. The electrical socket 2 has at least four side faces, and each side face can be provided with a terminal socket 21 or a group of overlapping terminal sockets 21, so as to maximize the use of the available space on the electrical socket 2 to set the terminal sockets 21, thereby facilitating the user's selection and use and effectively improving the applicability of the electrical socket 2.

[0084] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included within the protection scope of the present application.
